Hello, when using the flatpak steam, Proton games regularly hang when unredirecting in Gnome 40. This doesn’t happen when using native Steam. In journalctl I have the following error:

The final line shows an error with the Nvidia driver. It is always the same error and happens very frequently. It doesn’t crash the system, only the game but it is extremely annoying. Here are the bug reports for the steam flatpak: Proton games crashing when Alt-Tabbing · Issue #761 · flathub/com.valvesoftware.Steam · GitHub and for mutter: Some Flatpak Steam games crashing when alt-tabbing (#1830) · Issues · GNOME / mutter · GitLab
Running games with this extension enabled solves the issue: Disable unredirect fullscreen windows - GNOME Shell Extensions but comes with performance penalties and GSYNC doesn’t work.
