Bugzilla

Thanks again. So surface creation fails with `0x3000`. The spec (1) says:
> EGL_BAD_MATCH: Arguments are inconsistent (for example, a valid context requires buffers not supplied by a valid surface). 

We currently use the custom GLX based function`FindVisual` (2) to set to the appropriate visual for the window. The following build uses a fallback path with `gdk_screen_get_rgba_visual` instead - this *might* avoid the issue and gets rid of more GLX specific code - on mesa it appears to work just as well, I'm just not sure about non-composited window managers. OTOH I'm also not sure if I should care :)

If anyone could try and, whether it works or not, post the output - again that would be much appreciated.
