the last driver that I can use correctly for my Vega 64 is 21.5.2. Every single one after it gives me a black screen on my main monitor.
Here are some specs:
Ryzen 5 3600 on an ASRock B450 K4, 32GB 3200MHz RAM, Windows is on a WD Black SN750 NVMe SSD, my GPU is an ASUS branded one. I have Resizable BAR enabled.
I have the following monitors: Eizo S1921 (SXGA, 60Hz, HDMI->DVI), BenQ XL2411Z (FullHD, 144Hz, this one turns black, DualLink DVI), AOC 2590G5 (FullHD, 75Hz, FreeSync, DP).
If I update past 21.5.2 my main screen turns black. It still receives a Display Signal but does not show anything. With some versions this only happens after I reboot (it sucks if your main monitor is black for login and you don't know what's going on yet), with others it turns black right after the new driver activates.
I know that some driver versions listed behaviour like this (black screen when using displays with very different refresh-rates) as Known Issues, including 21.5.2 which is working for me, but version 21.2.1 already claimed this problem as being resolved.
I do not think it is acceptable for a fairly recent and (at the time) quite expensive GPU which is still relatively popular to have such a big driver issue for months now. Is there a workaround?
