[UI] Going from Windowed Mode to Fullscreen Mode ends up in a black screen

[Aingar]

Painfully aware of the issue which stems from the way FLUF interfaces with the game renderer. Several fixes were attempted that don't appear to have done much, if anything. A more robust fix is in the works, but no ETA at the moment.

A workaround is to turn off borderless window mode, since from what I'm aware it only occurs when that border mode is enabled (even if in fullscreen).

You can switch between the border/borderless modes in the FLUF config menu, you'll need to define a keybind to access it.
