Crazy Screenflicker

I got a “samsung odyssey g7 32” and in the cerim crucible i get alot of flicker.
Don´t know if this is a monitor problem or something else.
Nothing helped so far, what i tried to change.

It seems the fog is the problem, that causes the flicker.
But man … this is stupid. I don´t wanna buy a new monitor to get rid off.
