My Asus Tuf vg27aq Minimizing some games on launch and won't maximize. The screen goes black and seems to reset and then minimize the game. The problem started with elite dangerous and now it has spread to skater XL (which used to work ).

Using the display port on a 2070 super to get the higher frame rates.
Tried multiple ports, Turning on and off G-Sync and Overclocking.
