Sorry for being unclear about windows cursor. I have already tested all possible variations and tracked down the problem – the random black screens appear only while using -systemmouse in game, which overrides the in-game cursor with windows one.
Also, Moss doesn’t capture windows cursor (you can not see it in any of the moss report screenshots).
Just to clarify: if I use in game cursor it works properly and screen recorders do not interfere with the screenshots. I want to figure out if it’s possible to fix the black screens while using the windows cursor in game and display the cursor in moss screenshots?
