Summary: SDL game teeworlds crashes in r100_cs_track_texture_check Product: Mesa Version: 7.10 Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: alkisg@gmail.com

The SDL-based game "teeworlds" crashes on a laptop with Radeon IGP 330M/340M/350M [1002:4337] when KMS is used, but it runs fine when I use "nomodeset".

When I don't have "firmware-linux-nonfree" installed the game also doesn't crash but it's 20 times slower, about 1 fps. I tested on many recent Debian and Ubuntu versions - the output below is from Debian testing (Wheezy). I had to comment out "options radeon modeset=1" in /etc/modprobe.d/radeon-kms.conf for "nomodeset" to take effect.

I can attach more output upon request, or test with different software versions. Thank you.
