Here is the backtrace. I can't tell if this is a KDE bug or a Radeon bug, so I'm starting with the bottom layer. I compiled from git just yesterday (and restarted X) to ensure the latest code. If this is not a radeon problem, but is a KWin problem, please let me know any information that would be helpful to the KDE devs for resolving the issue and I'll open a bug report there. I have "ATI Technologies Inc Radeon HD 3870" video card (from lspci) Thanks, Application: KWin (kwin), signal: Aborted [KCrash Handler] #6 0x00007fbe18b7b445 in raise () from /lib/libc.so.6 #7

What version of mesa are you using?
mesa 7.8.2, xorg-server 1.8.1.902
Does mesa from git master work any better?
Ok, I've installed mesa from git, and, oddly, now the backtrace doesn't show function names in r600_dri.so... but obviously the fact I'm getting a backtrace again means I'm still hitting the problem. :-)
KDE devs recommended turning down my "Texture filter" from trilinear to bilinear, and I've not got any crashes since. Hopefully that helps narrow down the problem?
Note: classic r600 driver has been abandoned. Please use r600g (gallium driver) instead. Is this still an issue with a newer driver/kernel?
The classic r600 driver has been abandoned long ago. It was replaced by the Gallium driver r600g. If you have issues with r600g please file a new bug report with component Drivers/Gallium/r600 Thanks.
