[mythtv-users] Nehemiah Performance

Wed Sep 3 10:58:12 EDT 2003

Maybe I have the same GUI problem. Since upgrading to those newer VIA
display drivers the mythfrontend gui messes up completely any time it
tries to display a tree. The gui basically becomes unusable afterwards
because now none of the screens will paint correctly.

I'm still thinking about what would be the best way to try and solve
this. Getting the latest version of X from CVS for example.
