"kcmshell4 kwincompositing", disable blur effect (2nd tab) and set the scale method to smooth (3rd tab) for the records please also specify your gpu and mesa/driver version - in doubt run "kwin --replace&" fro konsole and post the output. Thanks. *** This bug has been marked as a duplicate of bug 270818 ***

Thomas, Thanks for your quick responce. If I understand this correctly, the bug is "resolved downstream". I believe my system us up-to-date. How do I fix this then? Thank you, Andras888
"resolved" does not mean "solved" - just that the bug is outside our scope (in the up/downstream case) and no open task. however, while being the same trigger and result, the other bug was caused by a software gl installation, but fglrx causes the very same. you can - try the radeon driver (xf86-video-ati/ati-dri) - try fglx with enforced direct rendering (late versions have been reported to be reliable) "KWIN_DIRECT_GL=1 kwin --replace &" - remain staying away from the ARB shader using code (as hinted) - ensure that this issue in fglrx is not caused by it's setup demands (afaik one has to run some script after un/installing it)
