I’m getting this too. My issue is that when I have Visual Studio open on my second monitor, the editor hangs. If I close it, it works fine.
Again, I’m talking about the editor hanging after playing a standalone game.
I can reproduce that when I drag my Visual Studio window on to the same monitor that is displaying my editor, the hang stops.
To narrow it down even further-- It doesn’t have to be visual studio. Watching a youtube video on a different monitor also creates the hang. Something to do with display adapter?
Hope that helps something.
