Public bug reported:
Binary package hint: xserver-xorg-video-intel
After upgrading from Intrepid to Jaunty recently, I found that the
general graphics performance is poor.
* With desktop effects on, window switching & minimize/maximize are horribly
slow and sluggish. Switching off desktop effects help a bit, but still the
following problems remain.
* The screen refresh is very poor and sometimes leaves the traces of other
windows in the current windows !
* Selecting text in Kate seems to cause a late refresh and the texts realign
themselves after selecting - again screen refresh
None of this used to happen in Intrepid with KDE 4.2. Unfortunately,
since I have upgraded, I couldn't get the log files from Intrepid, where
it was working fine !
Through ubuntuforums I learnt about UXA. After enabling UXA ('Option
"AccelMethod" "uxa"' in xorg.conf 'Device' section), all the above
problems were gone and it worked just fine as in Intrepid !! But there
are other problems like frequent system freezes and all
(https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
intel/+bug/342675) with UXA.
