There’s nowhere I can grab the window to drag it. It seems to just be stuck there, and even doing something like Windows Key + Shift + Right Arrow to switch the window to the other monitor does not work.
I had this same problem months and months ago, I had this persistent bug where the viewport would be borderless and anchored to the top left corner of my screen, while the studio window could move around as normal with a blank viewport section.
lasted about a week, reinstalling didn’t help, but when a studio update came out it was fixed
