Resolution Note:
This issue highlight a problem in the HDRP renderer design. HDRP made some render pass choice for performance reasons. Fixing this issue properly will have a perforce impact, thus the won't fix to not affect existing project. However there is a workaround. This issue only happen in deferred mode and with object that use object motion vector. For such case, the workaround is to enable a full depth prepass via "Depth prepass within Deferred" on the framesetting of the camera. This will fix the issue but have some cost on the CPU.
