i965/20.1: gray rendering with torcs racing
since the update to mesa 20.1 series (archlinux), I'm getting a gray rendering of track and background elements under torcs:
my hardware is an Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz (HD 4000 gpu) (sandy bridge)
reverting to 20.0.7 or earlier make the problem go away
