Bug Description

When using an OpenGL application that renders to an RGBA context, like Cairo-Dock2, the windows of any Qt-based application is invisible.
It happens with VLC, Smplayer, Skype, etc, and with any window manager.

to reproduce it :
launch cairo-dock with opengl :
cairo-dock -o
then open Smplayer.
=> the movie is invisible.
a workaround is to set the following :
export XLIB_SKIP_ARGB_VISUALS=1 && smplayer
Thanks to pay attention to this bug, since it has already been reported several month ago, by manu users, and has still not been fixed.
