--- Comment #12 from MC Return mc.return@gmx.net --- I am also affected by this bug, Gallium 0.4 on AMD HAWAII (DRM 2.43.0, LLVM 3.8.0), OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.0.2 (git-4c0b484) here.
It is quite painful as this is by far the best FOSS 3d scroll shooter around, for those interested, the homepage is here: http://www.viewizard.com/astromenace/index_linux.php

As I am running a 390X with Mesa 11.0.2 from git and had no problems before upgrading my card from a Radeon 6950 it is probably radeonsi related ? Could someone please test this with some modern GCN hardware on latest Mesa to confirm ?
