Screen flickers black repeatedly when activating performance overlay outside of a game
When I enter Game Mode and enable a performance overlay while not ingame, the screen starts rapidly going black and coming back.
If I manage to disable the overlay before the signal completely drops, the screen instantly returns to normal.

It's gone when I deactivate the Linux performance overlay from steam (I mean the one outside of gamescope in normal steam options)
Is this reproducible for anybody else?
