moonray_gui on MacOS leaks substantial memory when orbiting camera #166

raas_gui, or rather moonray_gui leaks memory when you use the interactive camera controls. Rendering the test curves.rdla file takes about 800MB of memory, but after interacting with the camera it balloons, I've seen it as high as 7.5GB before I closed it.

I see error messages like this

TBB MCRT thread pool                                                                                                                 ]   0.0% 
Context leak detected, msgtracer returned -1                                                                                         ]   0.0%

however I don't know if this is relevant.

Can you try with -exec_mode scalar or -exec_mode vector? We think this might be an XPU-mode bug.

We have found the problem and a fix is in the works.
