Bug 506530

SUMMARY
I am new to Linux, using the latest Bazzite OS. I’ve been playing final fantasy 16 with adaptive sync set to auto and the game running in borderless window. Consistently when i would close the game and return to desktop, the frame rates would be all over the place resulting in freesync flicker. Disabling and reenabling adaptive sync would stop. So far the “permanent “ fix is to run the game in exclusive fullscreen mode. As expected, when closing the game, the desktop refresh rate is pinned to 144hz rather than wildly fluctuating. 

STEPS TO REPRODUCE
1. Regularly playing the game in borderless window causes the issue upon closing
2. Disabling and enabling adaptive sync temporarily stops
3. 

OBSERVED RESULT
Extreme frame rate fluctuations and brightness flicker

EXPECTED RESULT
Stable frame rates on desktop with no brightness flicker
