please have a lok at the dupe, check the output of you glxinfo.
If the bug is reproducable and you don't understand the issues discussed in the dupe, please attach the output of glxinfo.

As a workaround you can disable the blur effect.

disabled blur and now working.
Comment 3 Thomas Lübking 2011-06-10 10:26:36 UTC
That's hardly a surprise - please ensure you're not somehow using the software renderer.
"glxinfo > my_glxinfo.txt" will dump the relevant information into a text file you can attach.

Comment 5 Thomas Lübking 2011-06-10 10:45:21 UTC
do you have "enable direct rendering" in the 3. tab of "kcmshell4 kwincompositing" checked off?
Comment 6 Mebuntu 2011-06-10 11:20:50 UTC
enable direct rendering is checked
