Stutter in screen scrolling

Right now with all the new kenels with have manage to approach 60fps. But it will never be smooth enough if we dont get the stutter fix.
Before u begin and say that your phone does not have the stutter, well it does. The problem is at any window such has contact if u swipe u get a very smooth scrolling but if you hold your finger and scroll very slowly u will see microstutter and not a smooth scrolling.
Im not sure if this has been posted before and dont know if it might be the screen or actual Os
Im holding the zune hd & iphone. Both device does not suffer from this microstutter

Strange I have no stutter using fresh 3.2 with stock kernel.

Strange I do have stutter using fresh 3.2 with stock kernel.
And I agree with OP. I knew I wasn't the only one who noticed this. When flicking through homescreens on launcher pro (or even sense) the scrolling is completely smooth. When you hold your finger on the screen and move it, it stutters and makes very tiny jumps. It's not appealing. It's great we've been able to crack the 30fps limit despite HTC's unhelpful attitude. I think the next step would be to get rid of the stuttering.

I have the same exact issue and have noticed this from day one. It's quite annoying. I thought the fix for fps would stop it, but I was wrong. I've tried to ignore it, but such a thing cannot be ignored by my eyes. It's noticeable every time and more annoying each time.

I have been bothered by this since day one also. its the only negative thing a colleague of mine (blackberry user) has to say when he compares iphone to evo. its there wether you notice or not

When "slowly" dragging my finger to change screens I see that initial stutter but I'm not seeing the "jumping." Or is it that initial stutter?
Usually flicking through the screens as fast as my finger can go and it looks smooth as a babies .... bowel movement.

it won't be noticeable until you have an iphone or zune hd, who ever saids that it's not there is because they have not notice it at all. i have use all fresh roms and still have it.
Go to a website or to contacts and swipe to scroll, you will see a very butter smooth scrolling. Have a iphone on hand and do the same, you'll that the smoothness is about the same. Now grab the screen with your finger and slowly without let in go of the finger scroll up or down. You'll see a microstutter which is very obvious when you compare it to a OS like iphone or Zune HD (and from video do not see it in wm7). Is very annoying. I have the iphone 4g next to me and can tell you that the scrolling between home screens are about the same smoothness wise (using launcher pro with king's kenel #8). But the microstutter is so obvious between devices that is to hard not to notice.
like i said, i'm not sure if this is due to the screen or what, i'll try it on my sister nexus but is good that could take a development look into this problem aswell.

Maybe a nova/epson difference. Because my nova does not stutter.

Nova is what i have at the moment and this happens. running Evio, my friend with me right now has an epson running fresh and does it has well.

The people who claim they don't have it are simply not seeing it, but it's definitely there. It's on my brother's evo, mine, and my friends.

Honestly have to say I forgot what the sense contacts evn look like..if even different from aosp cm6...but if memory serves it is slightly and I get a smooth scroll. Went to some image heavy sites and notices that pictures sorta pixelate a bit when slowly scrolling but text bodies and links scroll smooth when inching along. Using dolphin HD over stock if that counts for anything. Like I said I see a slight stutter on homescreens initially but it scrolls smooth and as said maybe the aosp isn't giving me issues. Not sure?

i have tried CM6 and still there. It will always be smooth with any rom, even more with cm6, but this is something else. Is something with how the screen detects the scrolling touch while holding it.
like i said before, you'll not really notice it much until you see an iphone and compare both side by side. Then you'll see the problem i'm talking about.

as a previous iPhone user, this was the first thing I noticed when I got the phone. the scrolling just isn't as smooth.

build.prop edits for droid x:
To enable better scrolling speed through lists, I changed
windowsmgr.max_events_per_sec=55
to
windowsmgr.max_events_per_sec=60
Scrolling through the app drawer and contacts and any lists really is now smoother

i dont know if this will work for the evo. i dont really notice a difference using cm6. perhaps others will have better luck.

It's only been about ten minutes since my last post but I don't see a HUGE difference. IMO this isn't worth doing. I wonder if this problem will ever be fixed. Oh well.

Xoom lag issues

Anyone else have lag issues when unlocked, rooted, with oc'd kernel installed running at any speed. I mostly notice when coming out of standby mode. Text input on web pages is considerably slow, also loading of web pages. When opening apps it doesn't seem to be affected other than movie playback. Any feedback would be appreciated.....

Oh one other thing....when I first installed OC it was running like wildfire, the longer I'm running it the worse it is getting. Yes the cache was cleared, any other ideas?
Sent from my Xoom using XDA Premium App

Same issue here, not sure of any fix though.

this happens to me too but it never lastes more than a min or two.

hmmm i havent noticed this at all. have been overclocked for a little over 2 weeks with only a couple restarts due to theme installs

i mean it isn't something that is super noticable for me but sometimes my keyboard lags for a couple mins but then it gets back to normal. i mean it is expected when you have a device that still hasn't had its "official full" update lol.

This makes my Captivate feel like butter. Apple has nothing to worry about.
Its disappointing, to say the least.

Yeah, but compare this experience with stock on the Captivate (cause it's not even close to Serendipity), and that's a whole different comparison
It took a while for good, stable kernels to come out for the Captivate as well. Hopefully Google changes their mind about the source code once the rest of these tablets start coming out, and then we might get some of your fantastic meals for the Xoom too!

No kidding. Flash back to stock Eclair on the Captivate to turbo charge your Xoom.

If you are running performance mode with setcpu and have a min freq above 250, the CPU will drop to 250 when you turn screen off and not go above it.
Simple fix is to keep setcpu on "on demand", but you can also keep it on performance and manually bump the freq up by going into setcpu every time you turn the screen on.

Yea, the only time i lags for me is when i am scrolling via browser or something with a lot of texts / graphics. I would assume a dual 1Ghz would be more smooth than this.

You have something wrong then. I do not have that experience. In fact, if I try to do some intense things like video recording using your Captivate ROM, my phone chokes where my Xoom does not. Granted, the Xoom does lag for me with certain things, mostly certain web sites in the browser including this site, the overall responsiveness has been just as good or better than my Captivate with your ROM.
Perhaps you should be more specific on what you have installed, how your screens are configured, what widgets you are using, etc. so maybe the culprit can be identified. Are you full stock with nothing installed and experiencing this?

I disagree. You have a bad unit or your doing something wrong. Back off the bashing.

This is true. When i had it set to performance i noticed significant lag. When i changed it to on demand it became much smoother.

Is there a fix for laggy/choppy scrolling w the Xoom? Perhaps a FPS increase?

I bought one. I love it. Do not want Ipad, I want to stay with Android and will.
However - the scrolling is not smooth, there is no denying that. Is there a way to fix this?
I remember when I first got my Evo I had to root and put in a kernel that increased FPS. Is there an option for that yet?
Thanks.

My scrolling is smooth - i am overclocked, have been since the first 5 minutes of taking it out of the box.
I thought that I read we didn't have a cap on the FPS.

Use a new launcher like launcher pro
Sent from my ADR6300 using XDA App

Ok. I'll try the LauncherPro when I get home. Thanks for the suggestion.
Did you get some choppiness before you switched launchers? Or before you OCed?

The stock launcher is very laggy... if you use launcher pro you can set how fast the menus open. Get spare parts out of the market and you can configure how fast either things open too
Sent from my ADR6300 using XDA App

The stock launcher is perfect. Really no need for a new launcher. I did experience some lagging but have to say that once I overclocked my XOOM it runs smooth as butter.

This is going to sound really stupid, but make sure it's right side up, in landscape orientation.
All other orientations are far less smooth (on the homescreen at least). Even 180 degree landscape is horrible. Only the standard orientation, with the Motorola logo in the top left, works well.

"SetCPU" to over-clock it and "VM Heap Tool" to increase the heap to above 32 (i set mine to the max(48?)). After that, my stock launcher is smooth as butter in any orientation.

Mine lags abit, so i take it I will have to root the xoom ? for increasing cpu?

Yes, you will need to root the Xoom. You can get the one-click root over on the Development side of this forum.

That is just retarded... in order to have my xoom running smooth and how it should, I have to root. Does that make sense to anyone.
This is not exceptable... FAIL
Sent from my Xoom using XDA App

The only time I found it not running smooth(before I rooted) is if i dragged my finger across the screen to scroll. If i just tapped the side, it was crisp.

Xoom or Doom!!!!
i guess it is all comes down to personal preference. cuz my Xoom is pretty smooth and i am running stock. i don't think anyone has a Super Xoom or a Doom Xoom. it is the same hardware, just that some people see fast different. get a thunderbolt if you wanna be super fast. or take the risk and overclok (something i'll never do), cuz there is obviously a risk factor to it. low battery for one, i won't be trading battery power for speed anytime soon. and then you xoom might not have a long life. it might be fast now, but we all watch nascar and see what happens when you go too fast, you CRASH!!!!. and within a year you could end you with a Doom Xoom. (dead Xoom).
cuz if this thing was safe to be overclock, i have said in other thread, uncle Moto would have been the one to do it, and would have brag and claim that they have the fastest tablet on the market @ 1.5Ghz. we all know it can be push even further. but with the cons, i won;t take my chances. i don;t need the nano second it will take to load an app, am fine with the extra second it will take me to load a web page. and scrolling is normal as it has been since i got mine. plus others have tried launcher pro and experience better. but do what you feel, just don;t come back crying foul about how you tablet didn;t last, and try to blame motorola for your fault.

How high are y'all overclocking? Hows the battery life?

Feedback on new AT&T ROM

So I installed it yesterday (and thanks to all those who helped).
I think the new ROM is FANTASTIC. Everything works for me, its faster than before and I have no lags. Im using Launcher Pro because the new Blur doesn't support scrolling widgets.
Battery is definitely better (turned on at 6am and had 15% at 6pn which us amazing for me).
Camera has been improved. Pictures look sharper and the colors no longer look weird. I owned an sgs2 and to me the pictures are just as good (and definitely better than the Sensation I owned for a bit). Its also much faster (put it in sport mode and virtually immediate).
Fingerprint reader works. Properly. Period.
Sound on speaker is excellent. Its still the best device on the market.
Sound on earpiece might be a little quieter. I am not certain on this but its something I noticed on my first call.
Gps lock is very quick. It was before too.
Software. Wow what a MASSIVE improvement. Email software is finally useable readable and possibly as good as Sense. Widgets are also better, like weather. Photo software and gallery better. MUSIC is a different application totally. I think I preferred the old one or just need to get used to it. Dialer is improved. Video playback is still great and again an area where this device excels over others I have owned. Animations also very cool. Top bar and notifications simply better than before. Entire color scheme is improved.
Stock keyboard is better but I still make a lot of mistakes when typing. HTC still make the best Android keyboard IMHO and I wish I could port the Sensation keyboard.
Overall its just more elegant and mire pleasurable ti use. For the first time I feel like its a device to show off. I really believe its the best device out there. Had Moto started out with this ROM it would have been considered a device as good as the HD2 in its day.

After one day on gingerbread, I'd have to say the keyboard's the biggest improvement for me. An @ key without having to press alt first? Yes! Long press keys for numbers? Yes!

I agree. It's a fantastic upgrade and the new skin is slick....my only complaint is that homescreen scrolling isn't as fast as I expected. The forest LWP is a little slow, and pinch to zoom on stock camera gallery isn't as good as my previous phone or 3rd party market apps

its is an amazing difference

before making the plunge I wud like to know from u guys about the screen gradient issues
is it solved??
like skin tones appeared really odd and washed out
I thot it was a software issue as the screen grabs also showed them on my PC
that was a big gripe for me but for the otherwise near perfect phone
and ya camera quality was also really poor

Are you talking about kenns?

I freakin love the new ROM. Thanks KP!

They have made a smart move by selecting a color scheme that greatly reduces the effect of the inherent technical limitations of a Pentile LCD! Its better than Froyo but I guess only because of the color scheme they have decided to go with!

Even if the color scheme didnt change its 10 times better. Im tired of the complaints about the phone, go get a different one and/or dont complain about this one. We dont care to hear it.

Loving the new rom so far. I do think the cardock app got worse (looks better, but fewer custom buttons). I love how you can uninstall apps using a long press from the app drawer.
I'm also looking forward to trying the ignore call, respond with text option.
Last thing, wish the default music app worked with Google Music Beta... installed the Google one instead.

Overall, this seems to be working pretty fantastically for me except for a few things.
- Contact List can get REALLY slow sometimes. (15 seconds to load up a contact's information!)
- Unlocking (the screen, not the phone) can get slow, as well as Facebook and a few other apps. Haven't fully tested yet.
Is this happening to anyone else?

So far, i'm loving the new blur, everything is working fine for me.but i hope this is not the final blur version, because i was watching a demo of blur for droid3 on youtube it looks a little bit better then this. The swipe between screens was different and the quick contact widget was different and more useful.

You only hard brick if you try to do the OTA. If you use kennethpenn's method using CWM with an unlocked bootloader you'll have no problem.

Just got an automatic software update for XXLQ2, Orange UK.

I turned my phone on earlier to find an automatic software update notification. So I downloaded it and installed it and it turned out to be ICS XXLQ2. Fantastic.
I have to say the phone is so much smoother now, I am using Go Launcher which was always quite laggy when swiping through home screens, now with ICS it is as smooth as butter.
Also love the new transitions between apps. The colour banding seems to be so much better too, although it's still not quite perfect. For example, my blue Go lock screen had terrible banding, really terrible, but now it's perfect. The bad colour banding on the backgrounds of angry birds has also disapeared. But on some of my own photos it is still there although not quite as bad.
Loving all the little tweaks, like the new swipe to close task manager, writing with the spen in s note is much smoother and more responsive. S Note is great. Apps open much faster.
Overall a great improvement to GB.
