Screenshot of the corruption
Description of problem:
When gdm has started I see glitches a little bit from the top left corner of the screen (screenshot provided) that comes and goes. The image in this distortion is sometime worse and sometimes better. And sometimes you can almost not see the distortion at all.
Version-Release number of selected component (if applicable):
I have an up to date system against updates testing.
Linux lillen.dodi 126.96.36.199-79.fc13.x86_64 #1 SMP Mon May 3 22:37:18 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux
Always there, more or less 95% of the time I use the computer.
Steps to Reproduce:
1. Start Fedora13, either liveusb or installed from it.
A part of the screen shows distorted versions of objects or other parts of the screen.
The screen should be consistent.
I also from time to time have problems with the colours of fonts. They can become grayis and also disappere (or maybe take the colour of the background, same thing visually). I do not know if this is related or another bug.
I have memories of having the same corruption like this while using Gentoo, nouveau and upgrading from xserver-1.6 to 1.7 (or if it was 1.5 to 1.6, cannot really remember any more). That time around it worked in Fedora, and talking to the guys in #nouveau they told me that Fedora had a workaround/hack that made Fedora12 work (like it still does), however that hack seems to have been dropped for Fedora 13.

Are you able to install the build at http://koji.fedoraproject.org/koji/taskinfo?taskID=2176109 and see if it helps your issue.
It should, the code was in F12 for this exact reason, but this should've been fixed elsewhere for F13, obviously not :)

Yes, all graphical glitches is gone with that build.

Heh, yeah, I guessed that was the reason for the fix not being present. If this is still not a "proper" fix and you need testing or info to iron it out, just shout at me.;)
I'd be interested in knowing how much vram your card has, and the memory bus width (if you know it by chance).
It's still not a proper fix, but I'll still put it into F13 as it's the only viable way of fixing it right now, and doesn't have much of an impact.
xorg-x11-drv-nouveau-0.0.16-5.20100423git13c1043.fc13 has been submitted as an update for Fedora 13.

According to gpu-z the memory size of the card is 1024MB, the bus width is 512 bits. It seems accurate with what I remeber when I bought the card.

Yeah, the hack has been "well tested" with Fedora 12, and not much time before F13 is released I can see what you mean.
Anyway if you need more info or have a patch or a build or anything you want to test, just drop me a line. I know my way around computers, but am not a codemonkey so I can do most stuff but help with the actual code.
xorg-x11-drv-nouveau-0.0.16-5.20100423git13c1043.fc13 has been pushed to the Fedora 13 stable repository. If problems still persist, please make note of it in this bug report.
