So glXMakeCurrent says
GLXBadCurrentWindow is generated if there are pending GL commands for
the previous context and the current drawable is a window that is no
longer valid.
This appears to be true, we don't seem to have cleared all the pending
GL commands
before, so we get this error.
Adding a glFinish into the glean test exit path, gets it past this,
but I've no idea if this is correct.
I then hit a GLXBadContext soon afterwards which suggest something
more is going wrong.
Probably need someone with some knowledge of GLX to tell me more.
Brian? Ian?
Dave.
