<pre>Using Mesa 19.1.0-devel (git-dacb11a585), iris performance is nearly the same
compared to i965: average FPS is 4 lower (80 using i965 versus 76 using iris),
minimum FPS is 16 lower (60 vs. 44) and maximum FPS is 3 lower (111 vs 108).
The game performance with iris increased 80% in one month. This is impressive.
Iris seems to be refusing to free memory or is freeing much less than it should
and it crashed with segmentation fault twice. It seems it is a different
problem from the BLORP one.
Messages when it crashed:
Thread 56 "OGL_Dispatch_33" received signal SIGSEGV, Segmentation fault.
