It could be luck that the Unity engine's errors flagged by valgrind result in a crash with radeonsi but not with i965. The best course of action at this point is to fix the errors in the Unity engine, then check if it still crashes with radeonsi. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx
