I have now the following in xorg.conf:
Option "AccelMethod" "XAA"
Option "EnablePageFlip" "true"
Option "TripleBuffer" "true"
In addition, I have set “Keep window thumbnails” to “Always” in System
Settings. It seems as if desktop effects are much more smooth now.
However, there is an interesting effect: If some “animation” is not so smooth
and I exactly repeat it then it is much smoother the second time. An example:
I move the mouse into the top left corner. An overview of all windows
appears. I click on some window. The window moves into the foreground but not
smoothly. I move the mouse to the top left corner a second time and click on
the same window. Now, the animation is smooth. If I had clicked on a
different window, it wouldn’t have been smooth.
Has anyone an idea why this is? Does KWin or some other component cache
