Created attachment 47642 [details] 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.

Created attachment 47643 [details] Screenshot of a corrupted icon. As you can see, only the lower half of the icon is corrupted.
Created attachment 47644 [details] Screenshot of corrupted xfce panel plugins. Here, parts of a previous screen (gdm login screen) shine through the lower half of the plugin widgets (gtk progress bar). I guess the gdm login screen was not active on any console at this time, so these are just remnants. Reloading the panel fixes it.
Created attachment 47645 [details] Screenshot of corrupted firefox toolbar Corruption can get quite nasty after a while. The ugly pink background once was a somewhat nicer image from some firefox persona theme. There are more of those corrupted icons too for those who got a taste of them ;-)
can you try with drm-radeon-fixes branch of my git trre? http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=shortlog;h=refs/heads/drm-radeon-fixes t enables cayman blitting support.
> - linux-3.0.0-rc1 with latest fixes from drm-2.6 git applied, up to 2a9e5862a38f7195931bd51788dc9ce68b28120c. Small inexactness on my part. I pulled from drm-radeon-testing branch, not master, which should already have the blitting support. I do not have all commits from the last 5 days though, the last one was "fix oops in ttm reserve when pageflipping (v2)". I might give 3.0.0-rc2 a try together with drm-radeon-fixes, but after glancing over the changelog I wonder if this is really going to help...
can you disable page flipping and try again? /me hasn't run compiz on cayman yet too much.
> can you disable page flipping and try again? It did not help, though it delayed the problems. However, I've upgraded to 3.0-rc2 and this solved all my problems. I'm not sure about this, but I think the problem was me pulling from drm-radeon-testing instead of only cherry-picking the latest commits. If this is really the case, I apologize for wasting your time. > /me hasn't run compiz on cayman yet too much. It works really great! Thanks for providing a better experience with the open-source drivers.
Unfortunately, I have to reopen this bug, as the corruption returned as soon as I tried to start a 3d game (naev: http://code.google.com/p/naev/). - some fonts in the menu were corrupted and unreadable - exiting back to the desktop shows the same corruption mentioned before (window decorations, icons) However, it's a bit better now, as it did not happen during normal desktop usage (till now).

Bug 27523 seems similar, but not identical to this one. https://bugs.freedesktop.org/show_bug.cgi?id=27523
I have similar experience on HD6990, usually I have horrible pixmap corruptions with random memory content. PM also doesn't work, and I have turned it off. Nexuiz works fine, but after using okular things go quite bad.
I thought it was time for an update, but unfortunately this is still not fixed in 3.1-rc9. Isn't there anything that can be done about this? All in all, the driver works mostly fine, but the corruptions are very annoying and disturbing.
I've been having progressing icon, font and widget corruption in KDE4 and firefox for a over year already. It is easy to trigger this if I scroll quickly through a PDF file in okular; heavy texture use or memory shortage trigger it reliably too. The symptoms are essentially the same as Harald described, although on a radeon 9600xt, opensuse 11.4, linux 3.1-rc5, Mesa 7.11.
(In reply to comment #13) > The symptoms are essentially the same as Harald described, although on a radeon > 9600xt, [...] That's probably a different issue from this one (which really seems Cayman specific) then. If you can still reproduce the problem with radeon.agpmode=-1, please file your own bug if there isn't one for your card (generation) yet.
I have the same symptoms here. Hardware is a radeon 6950 (Cayman) too.

This has been fixed with attachment 52762 [details] [review] from bug 40221. It does not occur anymore in kernel-3.2-rc1. I'm therefore happily closing this bug. Thanks.
