My preference for this one is to simply disable the feature altogether 
until someone does a top-to-bottom re-write of our
  use of wxGUI/PyGl that manages, as if by magic, to successfully skirt 
around all the bugs in OpenGL.  OpenGL is a farking
  minefield of "oh sorry, that feature is now a hardware dependent 
feature, and you don't have this weeks hardware, so,
  well, SEGFAULT".

Does the relatively-simple 2D rendering done by GNu Radio graphs really 
require OpenGL?  I"m not an expert, by any means,
  but those types of graphs (simple line graphs, and even the 
waterfall) were the sorts of things we were doing over 100Mbit
  connections to an X-terminal 20 years ago.  No OpenGL.
