Fabi - have you seen the same thing happening with figures as well as props? Any particular ones (I've only seen this on props so far).

Apart from that, this does look consistent - anyone else confirm? (hoping Tony/vilters will see this).

Steps to reproduce - 

1. load any prop item

2. set different level of preview and render subD in the Properties pane

3. render

4. moving prop in the preview should give a weird tearing effect.

5. re-rendering will not show tearing, and if the subD level is changed the effect will disappear.

If this behaviour is consistent from other users then I'll report it to SM so they can look into it ...
