Every now and then, my user interface completely disappears, including the mouse cursor. I cannot find any way of restoring it in game.
However, I accidentally discovered that it comes back if I ALT-TAB out of the game to another programme and then back to the game. This workaround is totally repeatable. Shared in case anybody else gets this problem.
It may only happen in DX12.
This is a new problem that I have only seen since updating to DX12/RTX3060Ti. Was OK in DX11/RTX2060 (now broken). Nothing else has changed.
