<pre>To reproduce, use:
- xonotic 0.7.0 at lowest detail, with only offset mapping turned on.
- r600g from git, with SB backend and LLVM both turned on. Turning off either
makes the bug disappear (although there are other issues, rensambling z
fighting, when only llvm is enabled; not sure if they are related to offset
mapping, I'll check later.)
The issue is clearly visible by running any of the demos that come with
xonotic. FWIW, other apps (glxgears, gnome-shell, etc.) work just fine.
$gitgl glxinfo | grep str
server glx vendor string: SGI
server glx version string: 1.4
client glx vendor string: Mesa Project and SGI
client glx version string: 1.4
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD CEDAR
OpenGL version string: 2.1 Mesa 9.2.0-devel (git-2923685)
OpenGL shading language version string: 1.30
$ llvm-config --version
3.3
Tested with both stock 3.10 kernel from arch linux and the recent dpm-wip5
branch.
Nothing suspicious in dmesg.
May be related to #50230, which was closed as fixed.</pre>
