texture issues in xonotic with llvm+sb and offset mapping
Submitted by Stefano Teso
Assigned to Default DRI bug account
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-29236857) 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.
