Yep - Thats what the debug logging I added showed me.

Nah - Doesn't seem necessary - I only had it on 1 min for re-mapping
the behavior of the existing screensaver-x11 code. I wonder if I could
determine that's the setting and log an info warning for users.

meh. I do like what that command shows me I can do though.

What I see happening is that the xscreensaver is kicking in and the
ant appears on the screen. Keypresses on the remote (pause and play)
don't always clear it. When I sent 'xdg-screensaver reset' the ant
stopped walking - I was still able to hear the video playing - but
nothing removed the ant from the screen. I'm guessing the ant was on
top of the stack and nothing was clearing, removing or painting over

Now 'xdg-screensaver reset' works as expected when the xscreensaver is
active and we're on the Watch Recordings screen.

There's probably no real problem here as long as the screensaver isn't
set at 1 min. That's the only way I've seen so far to have the
screensaver appear over running video.
