Symptoms

Mortal Kombat 11 doesn't render on Wayland session. It launches the game, shows splash screen, but the main game window is never rendered. Some other users reported black window only, in my case the window is not visible, but I can hear game sound. The only way to launch the game is to switch to X11, which is not a long term solution as X11 support will be removed from major DEs.

Reproduction

1. Install Mortal Kombat 11 (AppId: 976310) on Linux desktop
2. Launch the game on X11 session to ensure the game is properly installed and runs fine on your system
3. Switch to Wayland and run the game. You will either see a black window or no window at all.
