Bug#739801: mpv: Selected GLX FB config has no associated X visual issue

[Doug McMahon]

Package:mpv
Version:0.3.5-1

Due to 2 bugs in mesa  in around 15% of sessions when using xserver-1.15 mpv will use the default GLXFBconfig that has no visual id.
This will produce any number of visual glitches, wrong colors ect.
Prior to mpv commit67769db1a4e3a765c5f770f44f8b2b041a0246a9  in these cases mpv would just use xv & unless the user had specified  gl the vid would playback fine.
