> (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.
This Bug, or something similar, seems to be appearing with the latest
(beta) Drivers from Nvidia. Closing and reopening the Internal Videoplayer
causes an blank Screen.
