Again, I'd have to say that this currently sounds like a video driver
bug as other people running Yosemite with different graphics chips/drivers
have not reported this problem, or at least not yet.... I always advise
VMD users against being first-in-line to update to new OS versions,
particularly in the case of MacOS X, because they often break the video
drivers in the early versions of new OS releases. At present I don't
have any suggestion for a workaround, but I would suggest looking on
google to see if users of other high-end OpenGL apps have encountered
similar bugs on similar hardware. If anyone has further comments or
has observed this or other problems on Yosemite, I'd love to hear about it.
