--- Comment #5 from kristopher@posteo.net --- I guess it didn't sound like it from the original report, but the main problem is not that the border move is delayed. The problem is that the border stays on top off all other windows. The screenshot I attached shows the exact behaviour.
If I disallow the window manager to control the window, then the entire app is always on top, which is the opposite of what I'm looking for, a virtual desktop would do the same as well. But both of those just ignore the problem by forcing the window to not be able to go behind others.
