Thank you for looking into this. In the end update improved somethings for me (such as I no longer crash when alt+tab out of the game, unless I alt-tab aggressively and a lot). Therefore I believe there might be something additional what has changed. I also tried connecting HDMI cable directly to the laptop and disconnecting DisplayPort and after short look at it, it acts the same.
To clarify my findings: Session testing: - Wayland: DXVK_FILTER_DEVICE_NAME="NVIDIA" %command% works and the game (Devil May Cry 5 via Steam/Proton) runs stably. - X11/Xorg: DXVK_FILTER_DEVICE_NAME="NVIDIA" %command% does NOT work — the game fails to enumerate the NVIDIA adapter and crashes on startup with "Failed to enumerate adapters". The regression does appear worse on X11 than Wayland. Win+Shift+Arrow to move game windows between monitors does not work on either session, but I have found workarounds for that (Win+P to disable laptop screen, then re-enable after game launches on correct monitor). Downgrading libmutter-14-0, mutter-common, mutter-common-bin and gir1.2-mutter-14 to 46.2-1ubuntu0.24.04.14 partially restores behavior but Win+Shift+Arrow for game windows still does not work after downgrade. I am willing to provide additional logs or test specific scenarios if that would help narrow down which fix is causing the regression.
