Description Lukasz Krotowski 2011-01-25 12:45:48 UTC 
When running LO (OOo is also affected FWIW) screen is randomly corrupted (screenshot attached). And dmesg says something about unknown package in CS checker (logs attached).

System:
kernel: 2.6.37 + fairly recent drm-next merged (drm/radeon/kms: add quirk for Mac Radeon HD 2600 card), KMS
xserver: today git master
xf86-video-ati: today git master

Is this a recent regression?  If so when did it start?
Comment 5 Lukasz Krotowski 2011-01-25 13:42:53 UTC 
Frankly I don't know. I hardly use office suite on that PC (I don't see corruption on my other system: radeon driver with X1300, T60 laptop).

I know it's not connected with xserver upgrade because corruption was present with xserver git master from 2010-05-12 (I only upgraded to check if it makes a difference). On the other hand I upgrade xf86-video-ati fairly often.

I reckon I've spotted corruption when switched to LO (that big fork announcement). LO shows more corruption than OOo. And, IIRC, I was using drm-next at 2.6.35 level.
Comment 6 Lukasz Krotowski 2011-01-25 15:43:27 UTC 
FWIW I don't use compiz or any other compositing manager.
Comment 7 Michel Dänzer 2011-01-26 01:24:29 UTC 
Does it also happen without all the options you're enabling in xorg.conf?
Comment 8 Lukasz Krotowski 2011-01-27 00:36:12 UTC 
Good catch! Corruption is caused by Option "EXAVSync" "on".
Comment 9 Lukasz Krotowski 2011-01-27 03:09:52 UTC 
FWIW on my other machine (T60) I didn't have EXAVSync turned on. Turning it on also causes corruption.
Comment 10 Lukasz Krotowski 2014-11-14 15:22:16 UTC 
Closing, lots of time and git changes later I can't see any corruption.
