Screen turns to black after moving mouse

Does anyone encontered this issue? When I started UE4, the whole screen turns to black for 2~3 secs while moving the mouse, even at the create window or main control panel. Have updated to the latest GPU drive(2080S), I’m having a 2K res and 144hz screen, it just won’t stop refreshing and restarting over and over…

did u fixed the issue? Im with the same problem
