I remember reading a few days back about people having issues with screen tearing. My screen will display a symptom where it has a jagged line shoot across the center area of the screen real fast and then go away. I was wondering if anyone found a solution to that?

No progress has been made, yet. Some think it will be fixed in a software update. When I notified Google support of the issue, they thought it was a hardware problem, but if several people have the issue, maybe it's software.
I'm hoping it is fixed in a software update. That is literally the only issue I have with the tablet.

Yeah I hope so too, but I already have a replacement on the way. I have some other issues with mine though that I felt warranted getting a replacement.
Does the tearing happen to you all the time or just in certain apps? It only happens on mine when I'm playing music. It will show up for a split second as a quick horizontal line then disappear. The line appears in different areas of the screen each time. I notice it the most when it happens in Chrome, but I've seen it on the homescreen and in other apps as well.
Mine happens frequently throughout the ui. Xda app, chrome, everywhere really. If it is a software issue though there really is no point in exchanging. It seems to happen more frequently in an app with a light background.

I have this problem as well.. I only notice it in tapatalk though.. I'm not sure If its because I use tapatalk all the time or what..

Mine happens in chrome pretty regularly as well. Could it be something with the video drivers for this thing?

So apparently it was a bad kernel that I was using that caused the problems. Flashed a completely stock build and the problems are gone. To the people that chimed in and said they had the issue, are you on a stock ROM or did you change that and the kernel?

I've noticed this, but it's only happened twice (so far), Once was whilst using chrome, the other time just sat on the homescreen. I'm currently using stock.
(Not too worried, just as long as it's not a line of pixels about to give up the ghost as some other people have had).

Happens to me on stock rom. My N7 is not rooted or unlocked.
Pretty sure this only happens when you force GPU acceleration. I had the same issue, turned it off, and never saw it again.
Of course I love GPU acceleration too much to leave it off, but a jagged line every once in a while is not a deal-breaker for me.

Glad it worked for you, but I don't have that option on nor any other's enabled in the development menu. Regardless, the issue persists.
Is there anyone else having this issue?
I received a replacement today, but I couldn't escape defects on that on that one either. I'm trying to figure out if I should hang in there for a fix on the screen tearing/horizontal line issue, or if I should just send both back and call it a day.

I just found this thread. I have the same issue. I'm on stock kernel, unlocked/rooted, and stock rom. I don't have GPU acceleration forced.
Any further ideas? Could be a driver issue.

People here think the screen flickering issue could be resolved in software, but I'm not sure about the issue we are having.
I might go through the unlocking process just to see if the horizontal line stuff happens on other roms/kernels.
I really hope it can be addressed in a software update. I just struck out on my 3rd nexus. All of them have screen defects. All have had other issues like creaking and slight screen lift, but those are a lot less of a problem to me. The original one is ok except for the horizontal line issue. My two replacements each have dead pixels and dust in central areas of the screen.
This is ending up to be a very tiring and disappointing pursuit.
If it's a software problem it's likely to be in the tegra3 proprietary driver blobs. If this is indeed the case, changing rom and/or kernel will make little difference (because they share the same blobs).
It might be possible to work around the issue outside of the blobs but its likely only nvidia can fix the root cause.

Hopefully someone at Google watches some of these threads. I have 2 nexus 7s with this issue. Thanks for trying to save me the time of trying a different ROM/kernel, but I might still try a CM10 build for kicks.
My first tablet had one dead pixel and it had this issue too. My second one is perfect except for this problem. It probably does have to do with the tegra 3. I hope its a software issue because this one is perfect except for that one problem. I'm not rooted nor unlocked and no force GPU rendering either. It only occurs on some apps with mine. Tapatalk, facebook and barely ever on chrome. I haven't seen it on any games or video nor on the home screen. There should be a place to report this to Google... I doubt they are searching through xda looking for every little problem. I've had this issue for a while and have been searching specifically for bit and just found it today. Also I never see it in horizontal mode.

I have this issue too and I think it's likely to be a driver issue as it appearance seems random and sporadic in frequency, but it's always really hard to tell about these things.
In any I'm guessing some people just don't notice this issue and thus haven't really talked about it. But it sure is discomforting seeing it.
I seem to suffer from this too.. Everything is stock on mine, no mods, no flashes no unlocks.. It appears to be worse when its been on for a long time.. Wondering if its heat related?
Hey, has anyone else had a problem where, after weeks of a seemingly flawless n7, it starts to creak ? For me its when I put a bit of pressure on the right side of the screen and release.. its barely concerning, and after 3 rmas already I'm not sure if they'd let me do another, but do you think I should try? I definitely do not feel like opening up and fixing it by adjusting screws.. but A what if I get a defective one and B what if after so many Google says no :S thoughts ?

Sent from my MB855 using Tapatalk 2
I don't see anything wrong either. Is there something physically wrong with the screen? Screenshots won't show that obviously.
Unless you mean that the screen is shifted to the right, then the screen is fine. If it is because of shifting to the right, it might be more of an app issue not hardware.

I've got this issue, seems to be software related for me. It renders parts of the screen (ONLY grey area in settings, only place where I can get this colour atm). I will try re-flashing stock roms and trying different things to see if this issue can be fixed.
It's the background gradient in the settings. A solution would be to find the image and replace it. You'll have to dig through some apks though.

Hi. I have had this Nexus 4 for about a month and it has does some strange things with the graphics on the bottom bar of buttons. Please see the screenshots attached. It can happen every few minutes and as soon as I touch the screen it will revert to normal again.
Is this something that is likely to get fixed with an update or a hardware issue?
I can't find anything on the internet referring to the same problem but the sales guy in the local carphone warehouse has a nexus 4 as well and said his does the same :-/
Anybody know what is causing it.
Completely stock BTW oh and as you can see. Pressing the hardware buttons for a screenshot does not fix it. Only touching the screen.
Sent from my Nexus 4 using xda app-developers app
Wow.. thats not normal! I would look into RMA'ing that sucker!
You could try using a toolkit to reflash stock to see if that helps, however you will have to unlock the bootloader, flash stock rom and then relock bootloader, then you just go into settings and do a full reset to hide the developer options then you will be stock. The toolkit I use is this one http://forum.xda-developers.com/showthread.php?t=2015469 and its awesome just follow the on screen prompts.
I'm quite sure that this is a software issue, since hardware issues can't be captured by screenshots obviously. I'd recommend flashing it with whatever you like and do a factory reset. You can restore all apps afterwards ofc (use Titanium Backup for example).
Best regards!

That only means that it isn't an issue with the physical screen. It could still be an issue with the GPU or other hardware, since various hardware is used to create that software image in the first place.
I have seen exactly this sort of picture posted in at least one thread before on here before, though that might be hard to find on a search.
I would also recommend reinstalling the ROM and if it still happens then it must be hardware. I strongly suspect that it is the hardware.

Thanks for all the replies
I have now disabled HW overlays and it does seem to have fixed the issue (or at least made it far better, I have not noticed it since but it has only been an hour)
I will keep in eye on it for a bit and if it lasts cone back and change the title of the thread to solved.
Thanks for all the help guys.

hmmm, and the gpu just decides to screw up down there in a perfectly aligned rectangular shape that happens to resemble the navigationbar? i think thats unlikely.
gimpor, can you play gpu accelerated games? try please.
its probably googles weird 4 layer stuff. thats why disabling hw overlays fixes it. same guy that screwed up the kernel colors that merged it into 4.2.2 btw. : P
gimpor again,
hwoverlay is not permanent, a reboot unchecks it. try this
replace persist.hwc.mdpcomp.enable=true
with debug.mdpcomp.maxlayer=3
in your build.prop
or in the worst case persist.hwc.mdpcomp.enable=false
Its much better but still not fixed. Only done it once in about 8 hours whilst playing a solitaire game. I will try the other suggestions when I have decoded them into English :-/
I have not found any games that don't work yet, bad piggies etc. Seem to work okay. Would they be GPU accelerated?
Once again thanks for the assistance with this, it does get rather annoying when you show someone your phone and it's all garbled.
It still does this though :-/

Ya it was happening on stock as well for me too but I thought it was only my SMS I see you say others are having the same problem... Did you find out if it was hardware or software??? Have you done anything at all or is it still screwed???

I haven't found out anything further and it's still doing it but not as bad. It doesn't seem to happen to every stock phone so I'm guessing its hardware related, or at least something in software not playing well with this specific hardware. Mine is a 212 so they may have changed something on the later ones. I got it from Carphone warehouse on the UK as they were the only ones with stock. I had it changed already as the first one I got was DOA. I think it's going to have to go back if I can't get it fixed soon.

Guys. Sorry for kinda hijacking this thread but can anyone tell me what this is? It happens every time retract the keyboard and has been happening since first boot. I flashed factory IMG, factory reset and even formatted my phone. For some reason nothing. Again, i am just asking help. Thanks!
Any one else have a jittery screen? Occasionally my screen seems to glitch and like... I don't know... Fizzle to the right kind of and then returns to normal. Is this a known issue? Any one else have the issue I describe? I can't tell if it's the phone or the firmware (Stock), and if resetting it will work out or not. I think it's the phone personally and could classify as a manufacturers defect. Any thoughts?

That started happening to me too; I just thought it was an app freaking out. Every now and then it just jiggles left and right, as if it were shaking. Heck, I even had it happen in TWRP w/ Safestrap when doing a backup.
You have me worried about my own device now, lol.
I am on 4.1.2 and have not seen this issue before the update. I am rooted, but not unlocked.
Yea happens to me too never happened until the update
Sent from my XT907 using xda app-developers app
It happened to me before the update but not at all this bad, nor as noticeable.
Maybe it is software related them. This came with 4.1.1 just updated the other day and now it is definitely worse.

Mine does it as well. Looks similar to how the screen shakes when you enter the screen lock password incorrectly but seems to be random. Most likely a software issue.

Yeah, but, it happens way too much for it to be acceptable or normal. Simple as that, my phone should not be twitching.
It went from happening once or twice every other day, to happening more than ten to twenty times a day. That's unnecessary, and unbelievably annoying.
I think I'm going to call Motorola.

Happens to me as well, both at the lock screen and when using the phone, ( like browsing the internet) Most likely software related and not something to worry about
Mine does it too, seems to be common with this device.
I would assume firmware too, due to the above report of it happening in recovery.
It should still be brought to Motorola's attention in my opinion. It seems to be getting worse on my device though.

Happening to me to. I'm completely stock, non-rooted, running the latest OTA 4.1.2
Seems to be getting worse too
Happening to me since the update as well. Stock unrooted.
Also seems to be increasing in frequency.
Yeah my frequency is increasing as well here, and I'm thinking it's firmware / hardware, not software. Driver issue maybe? But I'm thinking it's mostly hardware related since most seem not to be having the issue we have, leading me to believe it's a manufacturer's defect
