Bug report: Uniform buffers not working correctly, Linux only

On Linux, our model editor window discards polygons from an animated model. This only occurs in the model editor window, which is a shared context with the other 3D rendering contexts. I believe the problem is related to the uniform buffers used to upload the bone data to the GPU; maybe they aren’t being shared properly between contexts:
