Description:
After upgrade to kerne 3.5.3-1 (i686) and running my GeForce 8400 GS under xf86-video-nouveau (both 1.0.1-1 from Extra and 1.0.2-1 from Testing), I experience screen corruption - apparently only under heavy load. Using the icewm WM this manifests as progressive corruption of: (1) gkrellm display (2) window borders / widgets (3) program icons. This first occured after browsing back and forth between a few high definition photos on Facebook (which reliably reproduces the crash). I have also run the ungine-heaven benchmark program from AUR and this very quickly produces the same outcome. Reverting to kernel 3.4.9-1 fixes the issue. There is nothing in my logs.

Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:
As above.
This task depends upon

I have subsequently tried with kernels 3.5.5-1 and 3.6.1 (from testing). Same result. Forum thread https://bbs.archlinux.org/viewtopic.php?id=149126 refers.

I am beginning to think that this may be a duplicate of, or related to,  FS#31330  (although I see progressive corruption rather than an outright crash). Other than the stress test of ungine-heaven, the only program which triggers the problem is firefox. I can browse the same high definition photos on Facebook using both Opera and Chromium, and there is no display corruption. Further: (1) the image (http://upload.wikimedia.org/wikipedia/commons/5/54/Lange-MigrantMother02.jpg), mentioned in the  FS#31330  report, provokes corruption, and (2) my graphics card has only 256Mb. I have not applied György Balló's patch, becuase nouveau_exa.c in my current xf86-video-nouveau 1.0.2 differs from that in 1.0.1. I will be happy to test any revised patch if that is considered useful.

status with recent kernels/Xorg/ddx drivers? does it help to fully remove nouveau-dri?
Comment by Geoff (perseus) - Friday, 28 December 2012, 21:13 GMT
I did not see any changes with kernel / nouveau versions down to those which are current. I worked around the problem by using Chromium for anything likely to involve heavy graphics load, and was caught out out occasionally by something unexpected when using Firefox. I did not try running without nouveau-dri. This week I installed a replacement card (Geforce 210 with 1GB of video ram) because I wanted to get rid of the problem entirely, and because I like to run Flightgear, which is not compatible with nouveau. I have therefore reverted to the nvidia binary (which I could not run before because of a different issue).
