20.1.3 is considerably better for reducing black screens in my case. I've been able to turn back on hardware acceleration for web browsers and Discord, and put them on my second monitor while playing games again.
Battlefield V has also been stable, but it can still crash at any time, because, you know, DICE. But no black screens.
I had one system lock up (not a black screen) when trying to close a browser tab with video playing, but it could just be a Chromium thing.
knocks on wood
