That does not at all sound normal. A stable system (linpack and furmark at the same time stable) shouldn't do that. It's not impossible for that to be a BIOS/EFI issue. Personally my 2060super with Debian stable has been a surprisingly pleasant experience.
At least you haven't gotten to the part where you can effectively(not literally) send hotplug events and such over displayport if you have two computers connected to one monitor. Kscreen gets a bit obnoxious in that situation. It wouldn't be too hard to send data between computers with that...
