Bug ID: 58838
           Summary: Unreal Engine's background fps limit has no effect
           Product: Wine
           Version: 10.17
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winewayland
          Assignee: [e-mail]

      Distribution: ---

I'm playing Vampire: The Masquerade Bloodlines 2 which is using Unreal Engine
5, and it has a setting for background fps limit - i.e. when the game detects
you Alt Tab-ing out (or minimizing the window) it's supposed to limit framerate
with something you can set low (like 30 fps or something).

However it doesn't detect it, which I suspect is a problem with winewayland
driver (though winex11 doesn't help with it either).

Not sure how exactly Unreal Engine does that detection though to narrow it
down.
