I started Dead By Daylight, and clicked the News button, and clicked the Survey link which opened in the Steam overlay.
It took me 30 minutes to complete it, I did a couple of ALT-TAB to go back to my desktop, and went back to the game closing and opening back the overlay to 'unbreak' the mouse clicks not registering in the opened page in the overlay (another issue probably to be reported).
Once I finished the survey, I closed the overlay, at this point, moving the mouse only one pixel would create a complete freeze of the game, for a split second, doing continuous mouse movement would completely freeze the game (even the Steam FPS counter wouldn't refresh or indicate a FPS drop) as long as I kept moving the mouse.
This issue reminds me this one https://github.com/ValveSoftware/Proton/issues/2875 where I could reproduce similar behavior (but it was only a huge FPS drop, probably here it is total freeze because I stayed 30 minutes in the overlay).
I did not reproduce this issue yet, I'll do later next week.
I can not define the mouse polling rate anymore because of current kernel not allowing it for some reason. Maybe this issue here is the same as before, and that could be fixed with modifying the mouse polling rate.. I can test with an old mouse which requests 125Hz polling rate instead of the 1000Hz polling rate my current mouse requests, if I can reproduce the issue with my current mouse reliably first, and see if I can NOT then reproduce the issue with the old mouse.
