When I Alt+Tab or use a Windows key to get out of a game (in this case World of Warcraft) and use a Windows feature or other program like Chrome, when I return to the game, I experience a 1-2 seconds black display.
This also happens when I use keyboard shortcuts to change volume and the Windows volume bar appear in game. I checked for graphics cards updates and also disabled Focus Assist in Windows, but the problem still persists.
I plugged my monitor to my motherboard and it looked fine anyway, but with changed settings in game.
I have 2x GTX 1070 Ti, and my monitor is LG 29" Wide Screen, and I run everything on Windows 10.
Do you have any idea or anyone have faced this problem ?
