I’ve always been wanting to use the HDR option, but when I activated it, every time I moved the mouse or when the mouse disappeared or reappeared, the screen flashed briefly. I turned it off and decided I’d try later after trying fixes from many online suggestions.
Well surprise! Today I tried it again, and I get no screen flashing. If you had the same problem, give it a try and see if it works for you too. Best of luck.
