 I think this mailinglist is the wrong place for such discussions. The 
 correct one would be kwin at kde.org or reporting bugs about it at 
 bugs.kde.org. I reply here nevertheless as there is incorrect 
 information. As a matter of fact the user would resolve the issue by 
 upgrading the drivers - Lanczos is disabled for Intel and Mesa >= 7.10 
 since KDE 4.6. For KDE 4.6 the recommended Mesa version is at least 
 7.10.

 This is not correct. There is a GUI option to disable the filter since 
 4.6 and the blacklist has been removed from master some weeks ago.

 We consider both blur and lanczos as an important part of our user 
 experience and therefore enable it by default for users with supported 
 hardware. It does not get enabled on hardware which does not support 
 these shaders in a satisfying way.
