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?
Just wondering whether the touch sensitivity has been fixed by a ROM?
Is it a hardware or software related problem?
Thanks

I think it's more hardware.

I think it can be improved with software.
It was done on other devices.
For example on the Galaxy S2 it is possible to increase touch sensitivity up to the point where you can type by just howering over the screen without even touching it.

I'm hoping too. My one x & iPhone have fantastic sensitivity but this when i tried one it clearly didn't.

My sensitivity has seemingly gotten better after installing AOKP and Faux123vs rom plus some touchscreen tweaks.

Which touchscreen tweaks please? And are you able to test using the Pointer location tool in developer options?
What is your Prs score?

Check this out, comment 40 and 42. Looks like its definitely software side, I'm sure google/LG will eventually fix it.
I have just ordered a nexus 4 and have seen on many reviews that this phone had some issued with pinch to zoom. Starting to zoom after you move your fingers for about 1cm. Is this bug still present? Are there any mods, kernels or custom roms that fixes it?
Thanks beforehand.

Nope. Not fixed yet. I am using paranoid android (and whatever kernel PA comes with).

The bug is still present on my device. Using rooted stock rom.
So far I don't think that any rom has "fixed" this issue... unless someone tells me otherwise.

This must be software related, because if a single finger draging is fast and responsive there is no reason a two finger pinch will not be. Hope they will fix in on next update.

I am starting to wonder if it's actually a feature...
my screen bottom and right side are not touchable as the attachment, bottom and right out of the blue line are not touchable. I'm not sure about the bottom area, but the right side surely became untouchable after I flashed a CM 10 rom, so I guess this is a software problem. yet reset and flash new ROM doesn't fix it. Is there anything i can try to fix it? much appreciate!
Never heard this kind of a software problem. I don't think it's a rom issue. May be your touch screen broken.
That looks like a sense ROM to me. Maybe your screen is messed like conzzy said

I'm having the same issue. Started when using a sense ROM, but the problem has persisted with a couple of CM ROMS as well, so figuring it's a hardware issue...

I think we have the same thing, and it is the reason i think it's a software problem that the issue came after flashing a ROM. But everyone believe it's a hardware issue, haha. Probably it's time to change a new phone.
I have the same problem too. The bottom part of the screen doesnt respond in some apps but responds in others. And its not like say it responds in whatsapp today it wont respond for whatsapp next time. If it doesnt respond for a certain app, thats it,it wont respond to that app again no matter what I tried. And I dont think its hardware related. Cause if it was, why would the area that doesnt respond for app A respond to app B. I dont really remember when it started but it started when I was using slimbean rom 4.2.

I don't know what happened but the other day my touchscreen started acting up. For some reason the knock on doesn't work at all, but knock off does. Also there is like a strip about a half inch from the top of my screen where the touchscreen just does not work. I can't click on anything in that area. I'm running OptimuS v 2.2

Not with stock KK ROM, nope. Maybe others can help you. Otherwise I'd recommend doing factory reset. If that doesn't help, returning to stock to see if it's the ROM or hardware.
Im having that same problem im on stock rom it has never been droped i dont know how to fix it and now it gives me an alert saying it detects my screen is broken although its not
