Public bug reported:
Yestarday i've updated my kubuntu (i update system nearly every day) and
today i found, that any plasma animations causes high CPU load and
immediately disabling kwin effects. After enabling by alt+shift+f12, any
plasma animation drops kwin effects again. X-restart as well as system
reboot didn't help. If i disable stability check in desktop effects
settings, kwin hangs with high CPU usage for a long time after
initiating any plasma animation.
Those of effects, that not related with plasma animation (kwin
translucancy, wobbly windows) are OK.
I took a look for install logs and found mesa-* there. Then i've downgraded
mesa-* to maverick version, and all seems ok after that. Then i saw this in
changelog for mesa:
== 7.10.2-0ubuntu2 ==
[ Felix Geyer ]
* Add 114_intel_dri_renderer_string.diff: Re-add "GEM" to the dri renderer
string of the intel driver. Removing it breaks KDE's detection for the blur
effect. (LP: #753370)
I have intel card and maybe this change is the cause.
