I can't move my windowed fullscreen app from the default monitor to my second
monitor. It tries to move but after one frame is drawn it reverts back to the
default monitor.

I suspect the regression is caused by 6a2e414d as this is the only relevant
change that came in 10.4 that wasn't in 10.3.

I reverted 6a2e414d and rebuilt 10.4 and now my windowed fullscreen application
won't open its main window at all.

wine output attached.
