Looking at it...

2 @0 glXCreateContextAttribsARB(dpy = 0x6c4f20, config = 0x72c1c0,
share_context = NULL, direct = True, attrib_list =
[GLX_CONTEXT_MAJOR_VERSION_ARB, 4, GLX_CONTEXT_MINOR_VERSION_ARB, 5, 0]) =
0x74cf10

don't do that? :) Mesa does not support GL 4.5, was that trace captured on some
proprietary driver that does? Can you change VTK (even temporarily) to only
request GL 3.0? Or alternatively flip to requesting a core context (which that
trace isn't doing) and request GL 3.2?
