The #COSMIC desktop environment, powered by the gay agenda.
The panel/dock run applets as separate processes that create a #Wayland window for the panel to display. So with a native Linux game like Celeste, that works with `SDL_VIDEODRIVER=wayland`, it's possible to run in a panel applet.
It "works" if you can play with a lot of the window cut off. I wonder if Gamescope could be used to do funny tricks with scaling (why not add a third Wayland compositor to the stack).
