--- Comment #7 from cyril.d...@gmail.com ---
Same here, i am unable to start Dota since mesa 17.3.1. The game crash just
after the Dota2 launch screen.
GLRenderThread[887]: segfault at 44 ip 00007ff219676ce0 sp 00007ff2174f3910
error 4 in i965_dri.so[7ff219261000+7f8000]
Reverting mesa to 17.2.6 "fix" the issue.
I am also on Archlinux and i have an i7-7500U.
Built mesa with debug symbols and attached gdb with the following command :
GAME_DEBUGGER=gdb steam
Here's the result :
Thread 4 "GLRenderThread" received signal SIGSEGV, Segmentation fault.
