If it works on Mesa 19.1.0 and doesn't work on 19.1.1, wouldn't the Mesa bugtracker be a better place to report this?
Yes, you're are right of course. It is more likely that my llvm 8.0 is old and mesa developers are using
svn.
If I'm off tomorrow I'll do a git bisect on mesa.
Recompiling 19.1.1 didn't give me a white screen. So, there is nothing to bisect. I did upgrade dxvk. Maybe that fixed it?
Nothing extracted yet.
There was a problem with the latest mesa point release. Mesa 19.1.1 gave me a white screen
when playing Assassin's Creed Syndicate. It painted the HUD, though .
I decided to downgrade back to 19.1.0.
