WINDOW_STATE: Putting W2 in the calc_showing queue
...
GEOMETRY: Clearing the move_resize queue
WINDOW_STATE: Removing W2 (Videos) from the move_resize queue
GEOMETRY: Constraining W2 (Videos) in move from 0,0 0x0 to 0,0 0x0
WORKAREA: Window W2 (Videos) monitor 0 has work area 0,0 1024 x 768
...

and then shortly after moved to the second monitor:

...
