Comment 2 Thomas Lübking 2010-11-09 16:43:33 UTC 
do not attempt to use trilinear filtering with ati chips - the drivers are
broken, sorry :-(

*** This bug has been marked as a duplicate of bug 243767 ***
Comment 3 acab 2010-11-09 18:24:39 UTC 
the crashes are new since update to KDE 4.5.2.
The filtering is bilinear.
Comment 4 Thomas Lübking 2010-11-10 01:34:33 UTC

/usr/src/debug/kdebase-workspace-4.5.2/kwin/lib/kwinglutils.cpp:643

is the source of the bug. the code says "glGenerateMipmap( mTarget );" and is part of the "mFilter == GL_LINEAR_MIPMAP_LINEAR" block, which means trilinear filtering is selected.

i've grepped the code, rechecked the options code and asked another developer - there's no other way in vanilla kwin to enter this codepath but using trilinear filtering.

-> ensure the option really says "Bilinear", then maybe contact your distro and ask whether they've hardwired trilinear for you :-(
Comment 5 Thomas Lübking 2010-11-11 20:41:11 UTC 
errr... didn't grep enough - my bad, i'm very sorry. (no, "really" ;-)

Actually ShaderEffects activate mipmapping "under the hood" - this would be either the "Sharpen" or the "Looking Glas" effect and disabling them should prevent this kind of segfault.

Sorry again =\
