Log event size mismatch as verbose

On rotation, it is expected that many successive events are ignored due
to size mismatch, when an event was generated from the mirroring window
having the old size, but was received on the device with the new size
(especially since mouse hover events are forwarded).

Do not flood the console with warnings.
