Radeon errors of kernel log during activation of kwin desktop effects

The kwin desktop effects are not rendering correctly in hardened. Had no issues until I reinstalled Gentoo with hardened/selinux profile. Selinux is in permissive mode and I pax softmode does not resolve the issue. There is nothing pax specific logged.

I had this issue from the beginning. However it somehow was gone for one user. The other user was not in group video. So I thought this might be the reason until I updated to KDE-4.11. Now it is there again.

Reproducable: always.

Actual Results:

Texture corruption of kwin desktop effects and logged radeon errors.

Expected Results:

Kwin desktop effects rendering properly. No radeon errors logged.

Additional Information:

e17 had similar radeon errors, but the textures itself did not look corrupted. I thought, unstability of enlightenment would be the reason and switched back to e16, which has not yet such effects. I'll attach the kernel log messages of radeon. Yes, I know, that most messages are logged twice. Maybe a misconfiguration of syslog-ng, but I checked syslog-ng.conf and don't see the reason for it.

glxgears does not cause any radeon errors in kernel log.

Corrupted window decorations during kwin desktop effects

I should have mentioned, that the corruptions mostly effects window decorations. But it effects also effects like zooming in and out of windows. Most effects are simply skipped.

[Comment 2 Manuel Ullmann 2013-12-15 21:52:16 UTC]

Forgot the Steps to Reproduce:
1. Start KDE with activated desktop effects (kwin) or press Alt+Shift+F12 to activate them as soon as KDE started.

[Comment 3 Manuel Ullmann 2013-12-18 18:03:55 UTC]

The following is multiple times printed to .xsession-errors during activation of kwin desktop effects:
radeon: The kernel rejected CS, see dmesg for more information.

for dmesg, see attachment 1 [details].

The Xrender backend is working fine. Only OpenGL backends are affected.

[Comment 5 Manuel Ullmann 2014-01-31 12:28:05 UTC]

This bug is fixed with hardened-sources-3.11.7. Marking this bug as resolved.
