SUMMARY
***
When I combine edge cropping and a shift (transformation with X offset), the preview does not show what is rendered.
***


STEPS TO REPRODUCE
1.  Insert a clip
2.  add transformation and edge crop operations (order does not matter)
3.  compare rendered output and project (pre)view.
See attachments for an example of the preview and settings, and what is rendered.


OBSERVED RESULT
Preview and rendered position of video are different. Notice that the blue "X" at the left is clipped in the rendered file, but not in the preview.

EXPECTED RESULT
The preview should correspond to what is rendered
