It's worth noting that the mythfrontend script sources /etc/mythtv/session-settings and as such it's possible to put the line:
export XLIB_SKIP_ARGB_VISUALS="1"
in that config file, rather than the mythfrontend script itself.
That worked for me, though if I tried to set mythfrontend to use the OpenGL painter (as I had under previous releases) rather than the Qt one then I get some nasty artifacts one menu transitions. So I went back to Qt.
