Description Darin McBride 2010-07-06 16:05:38 UTC

Application: kwin (4.4.90 (KDE 4.4.90 (KDE 4.5 RC1)))
KDE Platform Version: 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1)) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.34 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I'm not really sure what I was doing that might cause this.  It has happened a few times, I've even upgraded my video driver to the latest available (via git).

The crash can be reproduced some of the time.

-- Backtrace:

Comment 1 Thomas Lübking 2010-07-06 16:34:33 UTC

looks like a driver bug (esp. if you cannot tie it to a specific context, like closing a window or so)

-> disabling trilinear filtering should prevent crashes.
(bug should still be reported to the radeon developers)

Comment 2 Thomas Lübking 2010-07-06 16:41:49 UTC

additional info:
http://www.mail-archive.com/mesa3d-dev@lists.sourceforge.net/msg10283.html

seems that using glGenerateMipmapEXT() instead of glGenerateMipmap() works around this. (EXT/ARB conflict)

Comment 9 imperfectionisperfect 2010-11-23 00:57:46 UTC

How do I switch to glGenerateMipmapEXT() instead of glGenerateMipmap()??? I am used to editing an xorg.conf file, but I don't have one anymore.

Comment 10 Thomas Lübking 2010-11-23 15:10:19 UTC

you don't. that's a code thing and from what i can see in lib/kwinglutils_funcs.cpp:209 "glGenerateMipmap = (glGenerateMipmap_func) getProcAddress( "glGenerateMipmapEXT" );", kwin is even (unconditionally) using this already (would be funny if now that turned out to disturb ati chips :-) ... anyway: TLF has been replaced entirely for 4.6 and the lookingglas effect will be changed to not use it and "sharpen" is likely to be dropped

Comment 11 imperfectionisperfect 2010-11-24 04:19:29 UTC

Initially i believed that this error occured every time i attempted to enable desktop effects. However after further investigation, the crash only occurs if i have the texture filter set to trilinear. Hopefully this information can help someone.

Comment 12 Thomas Lübking 2010-11-24 16:56:33 UTC

yes... glGenerateMipmap is what you usually do for trilinear filtering - see comment #1
;-P

it's nevertheless a driver bug. it's a long time one. it's probably never fixed, that's (on reason) why TLF is replaced in 4.6
