[mythtv-users] 0.24 on OSX giving "NVDA(OpenGL): Channel exception"

[TJ Harris]

Is anyone else seeing this?

I recently upgraded to 0.24, on my Nvidia-based Mac Mini (original
NV-Mini, not the new thinner one).   When I have left MythFrontend
running when I power down my A/V environment, then later return, I
find my screen is corrupted and unusable.    I ssh into the Mini, so
it is still running fine, but I see errors in kernel.log.  Killing the
mythfrontend process does not clean up the screen, I have to reboot to
get it usable.

The errors I see are:

then, later (possibly when I resume the Mac) I get many of these logs
(maybe 50-100 per second):
