Gamescope doesn't work in most scenarios

I've been having a hard time running gamescope overall.

You can't run it with steam, and I understand it's just a fundemental flatpak issue, see issue #6.

But on heroic I'm having a lot of issue of trying to make it run:

• Trying to use -F fsr results in a blank screen.
• Using Mangohud AND gamescope will cause some issues, so you have to disable MangoHud for gamescope to work
  • Trying to launch minecraft with Prism Launcher mangohud gamescope -h 1440 -H 1080 -- just doesn't work. It gives an error: Failed to connect to wayland socket: /run/flatpak/wayland-0.
• Elder Scrolls Online via Heroic just doesn't want to run with gamescope, gamescope has the wayland icon on all 3 monitors but that's it, it never finished starting.

Ok I saw that there is an --mangoapp option which isn't documented anywhere but works. So that's -1 for mangohud.

ESO doesn't work with Wine-GE but does with Proton-GE so I don't know what's happening here. I did see that when using Proton-GE I don't get a kinda login error so it's most likely wine messing something up not allowing gamescope to run so that can be crossed.

The -F fsr issue seems to be ValveSoftware/gamescope#1237. I'll be closing this issue then as it's not something to do with the flatpak as I can see.
