STEPS TO REPRODUCE 1. open firefox 2. hit F11 for fullscreen 3. OBSERVED RESULT Screen refresh stops and page becomes stuck. It will take input but does not refresh screen. Hitting F11 again doesn't refresh screen to regular size. Manually closing window in task manager does not refresh screen. Other windows dragged on to that screen are not visible, though they do respond to input if you guess the position correctly. Requires log out or shell reload to drop last shown view. EXPECTED RESULT fullscreen then return to normal ADDITIONAL INFORMATION May be because using MOZ_ENABLE_WAYLAND switch when running Firefox so it's not using xwayland?
Correction: shell reload with `kquitapp5 plasmashell && kstart plasmashell` does not refresh that screen.
Logged error when hitting F11: radeon 0000:02:00.0: cannot be used for peer-to-peer DMA as the client and provider (0000:01:00.0) do not share an upstream bridge or whitelisted host bridge Can go to task bar and choose Move in that window's menu, move out from under frozen refresh and application is working fine.
Can you attach the session logs `~/.local/share/sddm/wayland-session.log` after making firefox fullscreen and the output of the following command `qdbus org.kde.KWin /KWin supportInformation` to this bug report please? and do you have a laptop with a discrete gpu?
Created attachment 145857 [details] wayland-session.log Attached is wayland-session.log, but it doesn't seem to log anything for the F11 push. I also notice it locks up the other FF window on another monitor attached to the same GPU, but not the FF sessions displayed by a second GPU. This isn't a laptop, it's a desktop with a RX560 and a HD7770 (which is the one the problems seem attached to), each running 3 monitors. I'm using the latest Arch opensource drivers for the cards (mesa 21.3.4-1).

Also, if I do an F11 on the RX560 attached FF session, there is no problem with it. `lspci -v | grep VGA` 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

Given "Logged error when hitting F11: radeon 0000:02:00.0: cannot be used for peer-to-peer DMA as the client and provider (0000:01:00.0) do not share an upstream bridge or whitelisted host bridge " in comment 2, this bug should be already fixed. Please reopen this bug report if the issue is back.
