Version: 0.1 (using KDE 4.0.98) Installed from: SuSE RPMs Compiler: gcc OS: Linux After having some massive performance problems with X server XAA acceleration using the Intel video drivers I changed it to EXA in the following way: /etc/X11/xorg.conf, adding options: Option "AccelMethod" "EXA" Option "MigrationHeuristic" "greedy" Option "ExaNoComposite" "false" /etc/environment, added entry: INTEL_BATCH=1 After that and restarting the computer, the hardware acceleration worked perfectly, but the KDE 4.1 systray is absolutely unusable. The whole systray is badly rendered. The rest od my desktop looks as usual and works. I will send you an attachment, if this will be possible here, later.
Created attachment 26198 [details] Snapshot showing the badly rendered systray after switching to EXA acceleration for Intel graphics hardware
I played with these settings and got to add the following remarks: - The relevant setting for this misbehaviour is Option "MigrationHeuristic" "greedy" which is an suboption of and depending on "AccelMethod" "EXA". - Setting this option to Option "MigrationHeuristic" "smart" Option "MigrationHeuristic" "always" the systray works (except of its usual flickering on changes), but the hardware acceleration isn't efficient and makes for instance longer wegpages in Konqueror scrolling very slowly.
