SUMMARY

Kdenlive doesn't act like expected when you enable the built in transform, add a rotoscoping mask and another transform effect on the stack.

STEPS TO REPRODUCE
1.  Add a clip with proxy to the timeline
2. Enable built-in effect and zoom in
3. Add a rotoscoping mask
4. Add another transform effect.

OBSERVED RESULT

The mask resizes and relocates when you add the second transform effect.
