[Openchrome-users] VM800: xv issues on Panel

[Martin Jürgens]

Hi!
Do you have any remaining ideas how to fix the problem? I'd be really
happy to see it fixed.

By the way: In the VIA drivers, the problem does not appear, so maybe
you can adopt something from there?

Thanks for your efforts,
Martin
