Motion Blur causes weird geometry glitching

[jonas_schneider]

Hello,

I recently came across a bug/issue I cant really wrap my head around. In my scene I have slow moving object. Nothing crazy. When I have motion blur enabled tho, some of the objects are randomly acting out, like this example:



The issue can be nailed down to the motion blur for sure. When I disable it, everything works just fine. This whole object is a instance (not just the geo that reacts) and only animated around the Y axis. I tried it as a render instance and normal instance. Any Idea what could cause it?
