I have tried this on Proton 9.0 beta and Proton experimental. I have also had it occur a single time on Proton 8, but it happens every single time in Proton 9.
Gamescope does solve the issue, but I lose controller connection, so that's not an option for me.
When I start a game with Proton 9 or experimental, if the game is fullscreen, the image will freeze. The game continues running, the mouse can interact with menus, and the sound continues to play. Doing another alt+tab out and back into the game will update the frozen image to what should be there, but it does not continuously update the screen, rendering the game unplayable until restarting it.
I am running this on a laptop, and I should mention that this only occurs when the game is running on my external monitor. Moving the game to the laptop screen does not have this issue.
I'm happy to upload any necessary logs, but I'm not sure what ones are necessary or where they are.
I have not seen this occur in a while. It is most likely related to KDE_DRM_SCANOUT as a nearly identical issue that I had was resolved by modifying that option
