(thinkpad edge14 w/ i3-370M(2.4GHz), 4GB RAM, Intel HD Graphics & Kubuntu 11.04 x64)
Extreme slow down in performance/extreme choppy graphics performance starting only recently after a system update that brought along w/ it Firefox5beta.
Switching over to xrender seems to have solved the issues. I much prefer to stay under xrender because the system seems to run/looks much smoother than under OpenGL:
1. Are there any benefits to running under OpenGL over Xrender?
2. Only feature that I miss is the blur effect under the taskbar; is there any way to emulate the blur effect under xrender w/ qtcurve and oxygen desktop theme?
3. The only performance related issue that I've noticed under Xrender was when running Diablo II:LOD under wine. Are there any tweaks/patches/configuration to ensure smooth graphics performance (game play and video playback) w/ xrender?
Any help that anyone can provide would be very much appreciated.
