From what I've gathered from the mythtv-users list, it seems that when a
screensaver has activated, it draws over the vdpau colorkey, so when
playback resumes, the video no longer displays. Seems the simplest way to
do this is to refresh the colorkey when coming out of pause (seems to make
sense since that's also when we turn off the screen saver/DPMS). I'm not
100% familiar with the code, but it seems like we could call
videoOutput->DrawUnusedRects() from inside the NuppleVideoPlayer() which
might solve the issue.

Comment:

Can you try the attached patch. I can't test myself as the Gnome
screensavers seem to be broken on both my systems.

thnks, Mark

Comment(by anonymous):

I'm actually seeing this with xscreensaver (since gnome is busted on my
system as well due to ubuntu 9.10). But I'll try out the patch tonight and
let you know if that fixes things.

Comment(by fracmak):

Nope, does not fix the issue. I was able to get it to work by added

videoOutput->ExposeEvent();

But I don't know if that's a hack or not, seems to be the only way to tell
the window it needs to be redrawn. Not certain what the ramifications are
for other renderers either.

Comment:

(In [22905]) Ensure the VDPAU colorkey is repainted when unpausing video
playback.
Prevents blank screens after a pause in which the screensaver has
overwritten the colorkey. Closes #7641.
