VDuring the opening of Ubisoft Connect, there is no black screen; the entire opening process appears on the screen. The screen only goes black when the game actually starts.
VI also tested it with Proton GE Latest and the same thing happens.
VI did several more tests and my conclusion is:
- Mangohud needs x11 and cannot use expose-wayland.
- Expose-wayland coincidentally worked to open the game but its not necessary
- Gamescope WSI 1 worked at times, but disabling it ensured I wouldn't get a black screen.
- I stopped using expose-wayland and the Mango app worked, but...
- The framerate limit didn't work at all, even when Gamescope WSI was enabled; the Mango app's FPS limiter didn't work either.
