I have a docked window on the right side (nav menu), when I open a window in the remaining area, IF it is not full height of the screen resolution the window does not open at 0,0, but lower see image. The project is started in full screen mode. I tested without the docked screen and it opens at 0,0.
The menu bar/Windows menu are turned off at the top (issues occurs when these are on also).
I tried loading the docked 1st or last, same issue.
