Xorg.0.log
I don't know where this should go (drm, mesa?), but after a while, I notice
corruption of textures / pixmaps. It can be reproduced quite easily by opening
a few applications, or starting another X session. In particular, I could
determine the following:
- Corrupted areas resemble parts of the previous visible login screen
- Icons, fonts and widgets like vertical gtk progressbars get corrupted, but
only their lower half
- Window (emerald) decoration seem to get corrupted completely.
- It's not related to color tiling.
- Pageflipping is enabled.
- Restarting a corrupted application fixes it temporarily, while minimizing
etc. doesn't. Restarting compiz doesn't fix it either.
I believe this is specific to cayman, as the issue does not occur on a thinkpad
t400 with ATI Mobility Radeon HD 3400 and similar configuration.
Software configuration:
- linux-3.0.0-rc1 with latest fixes from drm-2.6 git applied, up to
2a9e5862a38f7195931bd51788dc9ce68b28120c.
- r600g from git mesa compiled on 12:44:56 03.06.2011
- xorg-server 1.10.2
- libdrm git 21:06:43 02.06.2011
- xf86-video-ati git 21:56:58 02.06.2011
