Reinforces my notion that OpenGL is broken in so many fundamental ways.

You can't reliably predict what an OpenGL app is going to do on any random hardware. The implementations seem to routinely break the traditions of abstraction. It's downright infuriating. Simple 2D graphics such as is used in Gnu Radio should "just work", regardless of the hardware. I mean, if the freaking login window can render, then Gnu Radio apps
  should be able to.
