Red Hat Bugzilla – Bug 443080
compiz + intel performance in the crapper
Last modified: 2013-01-09 23:40:20 EST
Description of problem:
Previously, I was running into bug 435969, so I've not run compiz much since
moving from F8 to rawhide on my laptop. Worked great in F8, performance was
good, etc., etc. Machine in question is a Lenovo ThinkPad T61 with "Intel
Corporation Mobile GM965/GL960 Integrated Graphics Controller rev 12".
So no more compiz crashes, but UI performance has gone absolutely in the
crapper. Text shows up on screen well after I finish the next word (I type well,
but not *that* well), large window redraws take several seconds sometimes,
alt-tabbing between windows takes a few seconds to complete with jerky
animations, etc. Simply switching from one window to another by clicking (i.e.,
no animations in play) drives Xorg cpu usage up abnormally high (>60% usage of a
core 2 duo 2.2 core reported by top).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Nb: Jesse has more or less the same graphics on his laptop, was also hitting
alt-tab crashes until now, but performance with compiz on his laptop appears to
be on par with what I saw in F8 on mine. Ngggh.
