I tried cascading windows and it shows a gap as if there is a window there but agian it is literally just invisible. When I hit Win+Tab I can see it among the active windows but selecting it, or even trying to drop it to a second desktop does not resolve the issue. When I tell my computer to pane the windows sideway/stacked with only RStudio and one other app open, half the screen is blank so it's quite literally as if the window is invisible. When I launch RStudio from either the taskbar or start menu, the icon on the taskbar lights up as if it has opened but I cannot see a window.
