You can note your issue below here
I am playing Total War: Warhammer 3 that has been ported by Feral Interactive.
I have 2 problems currently. First (less impact) left mouse click will intermittently cease to work. After clicking around and pressing esc a few times it'll begin to function normally.

The bigger problem is harder to explain so here is an imgur link. https://imgur.com/gallery/ltCUsZS
The game will continue to run and I can still click on things. Any ideas?
