I'm sorry but I have to insist oin this bug, it can't be ignored so easily.
It happens on any graphic card (Nvidia, ATI, probably Intel too), and a workaround exists, so it can't just be a "driver issue"
the VLC devs said that the problem comes from the Qt widget, which creates by default an RGBA context, when most application would just need an RGB one.
for instance, if VLC could allocate an RGB widget, there wouldn't be this problem any more.
they had to make a dirty hack (hardcode the XLIB_SKIP_ARGB_VISUALS variable to 1).
This is not a correct answer, at least Qt has to provide a way to avoid such hack, (the best would of course be to solve the bug definitely).
