Shif focus causes tiled-below window to pop up over fullscreen on one of several monitors
Hi. When I make a window fullscreen with F11, and then shift focus to a window on my second monitor outside this "fullscreened" window, another window, on the first monitor will pop up on top of the fullscren window, obstructing its view and needs to be minimized. This probably a window "below" the fullscreen one, in the tiling order.
This concerns any application that can be fullscrened with F11; namely Firefox, terminal emulators, SM(video)player, VLC, and so on.
To reproduce; open two windows of the file manager (for example), unmaximized, on one monitor, and then a window of i.e. xfce4-terminal. Shif the focus to one of the FM-windows, then the other, and finally the terminal. Now, without shifting focus from terminal, press F11. Now, on a different monitor (extended desktop), shift focus to another window on another monitor, and one of the file-managers on the first monitor will pop up on top of the terminal, which is in fullscreen mode.
Since I have focus set to follow my mouse cursor, this happens any time I move my cursor on top of a window on another monitor when a window is fullscreen. I believe this is related to tiling/order.
