Same issue here, but with only one monitor and a 20-series card.
Some other random things that may or may not be related:
- I’m working with multiple copies of Unreal running
- I keep all tabs docked in the same window rather than opening new ones
- All of my UI layout is left as pretty much default
-When I switch to and from Unreal I primarily use alt + tab. Maybe that has something to do with it missing?
