[Bug 461817] Re: visual bug with OpenGL application

[Fabounet]

ok I'll do that when I'm at home, but I can add that this bug happens for
everybody (you can search on the net, it is already noticed several times).
also, a workaround is to start the Qt-based application with the following
command :
*export* XLIB_SKIP_ARGB_VISUALS=1 && *vlc*
(for vlc for exemple)
Hope this is a clue for you.
