Comment(by danielk):

 (In [13769]) Refs #2287. Workaround for an apparent nvidia bug that caused
 blank screens after video rendering method changes.

 The problem was noticed by Stanley Kamithi and worked around by Mark
 Kendal. The video playback window would be blank when switching from
 OpenGL to XvMC rendering with 8776 and crash when using the 9755 drivers,
 This may have something to do with the change to using the 3D pipeline to
 emulate XVideo in the newer drivers. The workaround was simply to unmap
 and map the subwindow with the OpenGL context instead of deleting and
 recreating it as we switch between rendering methods. The window and
 context are still properly deleted when we delete VideoOutputXv at
 playback shutdown.
