[mythtv-users] a video quirk with mythgame -> supertux

[cal]

My grandkids absolutely love a selection of the games my Linux
systems have provided, so setting up their myth system to give
access via mythgame has been quite a hit. Most games just work
very nicely, but a with handful, the video condenses into a
thin blue line across the top of the screen. Supertux is the
prime subject of the problem reports.

My system deals with supertux ok, so there's something funky
about the video on their box. Yet in all other aspects, the video
performance is just fine. The card is an nvidia 5200, and I've
tried all the recent driver versions without any joy.

If anyone has seen & resolved this kind of issue with games, I'd
love to hear about it.

cheers, Cal
