I've tried disabling fullscreen optimisations in both registry and on a per-game basis, reinstalled drivers several times, turned off Game DVR and just about everything else I could find by googling.
If I reinstall the drivers, it works, but as soon as I restart my computer it stops working.
Is this a driver bug or is there something I haven't tried yet?
5700 XT on 19.10.1.
I have the same issue and also I cant record anymore in CSGO and several other games with 19.10.1.
I got the message "disabled due protected content".
Update: I noticed that toggling Virtual Super Resolution in the driver settings fixes this, at least until the next restart.
It doesn't seem to matter if the toggle is to on or off, it's just the action of toggling at all that appears to work.
Good to hear for you unfortunately but it didn't resolve the issue for me.
I downgrade to 19.9.3. for now and waiting for the next october update or november release.
