Bug 476606 – kde-base/kwin-4.10.4: crashes after unlocking session when locked for 8-10 hours and foss radeon driver is used

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Nikoli 2013-07-12 03:32:53 UTC]

With FOSS radeon driver kwin crashes after unlocking session when it was locked for several (8-10) hours. If it was locked only for several minutes it will not crash. Sometimes it does not crash even when locked for hours. No 3D apps are working until X is restarted. dmesg is full of such messages:

Seems the problem is well known and fixed in kwin-4.10.3 and mesa-9.1.3, user needs update both for fixing them problem. kwin-4.10.4 is now marked stable, but mesa-9.1.3 is not yet.

glxgears does not work until X server is restarted, after restarting KDE session it works fine again.

Blocking bug is fixed, so i guess this is fixed too.
