SUMMARY

On some games, when you select the "windowed fullscreen" option, the panel stays visible on top of them.

STEPS TO REPRODUCE
1. Start Path of Exile 2 or Teenage Mutant Ninja Turtles: Shredder's Revenge
2. Make sure they started in Windowed Fullscreen mode
3. Observe issue.

Seems like this doesn't happen with the most common DirectX + Proton setup. But here we have a Vulkan + Proton game, and one Linux native game as examples.
