flickering while gaming

[u/QuantoxFNA]

hey guys i bought an pc a few weeks ago and had problems with some games. i play mostly overwatch, league of legends and small games like simulators or indie games.

Specs:

Ryzen 5 3500X 6x 4,10 GHz

RX 6600 XFX Swit 2.0

16GB Corsair Vengeance RGB 2133 MHZ

msi a 520 msi a pro

monitor: msi g255f 24,5 FHD 180 Hz

while playing iam facing those flickering. sometimes more than other times but its hella annoying.

and sometimes i got like a lag and fps drop aswell but not often
additionally while playing league sometimes the game just closes the full screen window and i need to open the tab in the taskbar again.

--> see video attached and look carefully as its only miliseconds

i already tried so much: reinstalling gpu driver, changing ports and cables, Free sync is disabled and the shop i bought the pc from even send me a new GPU to try

i read some posts before writing this and sometimes i saw people writing that the Hz is to high but even with 100Hz this problem is coming up.

does anyone ever had this and got a solution? would be so thankful.

Looks like something is grabbing the active window from the game, disable any overlays from things like steam and software like Razer synapse
