Hello!
When I play games and I Alt+Tab or try to change the volume from my keyboard's hotkey, the screen turns black, flashes couple of times and I get the message from the picture below(Display driver failed to start). Windows then sets the display driver to default, so it switches to integrated video card. I was given this message in the Device Manager:
"Windows has stopped this device because it has reported problems. (Code 43)" I have the latest driver installed.
Well, I reverted back to Radeon Software Adrenalin 2019 Edition 19.12.1 and this fixed everything. The Adrenalin 2020 (both versions) seem to be the problem.
