[mythtv-users] Screensaver leaves black screen after resume with OpenGL painter

[Karl Newman]

I use the glslideshow module of the xscreensaver package (version
5.15-r1) to show my photos when myth is idle. With 0.25-fixes,
unfortunately it seems that once the screensaver activates, it leaves
myth with a black screen after deactivation of the screen saver when
using the Auto or OpenGL painter. This happens with both mythwelcome
and mythfrontend in the GUI or with video playback paused (using VAAPI
or OpenGL playback profiles). The interface still responds to lirc
events, but the screen is permanently black until the app in question
is closed and restarted.

I'm on Gentoo amd64, kernel 3.4.0-gentoo, Intel core i3 (sandy bridge)
using the built-in video, with mesa version 8.0.3 and xf86-video-intel
version 2.19.0. For mesa, the classic driver is selected. Output of
mythfrontend --version:

I'd like to keep using the screen saver; it helps prevent burn-in on
my CRT and it's my grandma's favorite entertainment when she visits
(although she's a fan of Mythbusters, too--pretty cool for a
90-year-old lady!).

I'd welcome any ideas or further testing suggestions.

Thanks,

Karl
