while executing: War Thunder (PC game) on Arch linux - 

$ uname -a

--- Comment #2 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Does this still happen with mesa 10.6.1 (or mesa-git)?

I believe commit
http://cgit.freedesktop.org/mesa/mesa/commit/?id=78d58e642549fbf340fdb4fca06720d2891216a8
(which was backported to 10.5.9 and 10.6.1) should help with your issue.
