(BlendLuxCore alpha4, w7)
eg
1. Motion Blur ON
2. Motion Blur OFF

Re: Glossy with Camera Motion Blur bug
In your .blend file, only object motion blur is enabled, not camera motion blur.
Just saying because you wrote "Camera Motion Blur" in your post.

Re: Glossy with Object Motion Blur bug
narrowed down to Object (bug only appears when Object is checked/enabled)
ps
used an updated BlendLuxCore from current master
edit: above mentioned build crashes instantly when rendering with OCL (noticed it first when i tested the updated pyluxcore.pyd)

Re: Glossy with Object Motion Blur bug
There were 3 problems. One was general when rendering any anisotropic material (metal, glossy, etc. with uroughness != vroughness) on GPUs. The second was about motion blur support on CPUs. I fixed both:
The last one: https://github.com/LuxCoreRender/LuxCor ... ry.cpp#L77
I guess it is time to write the motion blur support there
