These things, I tend to install things from backports as they seem useful, not neccesarily just because they exist:

I didn't have backports graphics firmware. I've now installed it. Good suggestion. I'll see if that makes any difference:
firmware-amd-graphics/buster-backports,buster-backports,now 20210315-2~bpo10+1 all [installed]
Reporting as (after backports firmware install):

To my knowledge there is, by design, nothing X related in backports. I've looked for xserver and gnome packages and discovered that nothing GUI is included in backports, though I can't remember exactly where I found that.
It's a possibility, but this problem has been present over two different radeon videocards. The previous one a ASUS ATI/Radeon 512Mb HD5450, which exhibited the same behaviour. I upgraded to this 2Gb R7 240, which didn't change anything. I'll wait for the official bullseye release and then upgrade. This system runs a VM that does the load balancing for my home network, so I can't take it offline while the better half is busy with endless Teams meetings, it requires a little planning, so I'd prefer just doing it once when bullsseye goes to stable. So far I'm suspecting that the problem is related to gnome-extensions, with those disabled it certainly behaves alot better. That wasn't a problem under Ubuntu though, so I'm guessing there is an issue with gnome versions somewhere there. Thanks for the responses so far, EJ |
