Description paleh 2023-12-12 20:00:12 UTC
SUMMARY
When adding a frame in the animation curves docker before the first existing frame, the coordinate system of the transform mask changes.


STEPS TO REPRODUCE
1. Create a non-empty paint layer, add a transform mask to it. Select the mask.
2. In the animation curves docker add a frame to it at t = A, A >= 1.
3. Using the transform tool, make a change to the mask at A, e.g. a rotation.
4. Add a frame at t = B, B < A.

OBSERVED RESULT
After adding the frame, the layer at B is now placed with its center in the upper left corner of the canvas. 

EXPECTED RESULT
After adding the frame at B, the layer should be exactly as if the transform mask was not there.

SOFTWARE/OS VERSIONS
Linux: Ubuntu 22.04
Qt Version: 5.15.7
Appimage

Comment 1 Dmitry Kazakov 2024-01-11 11:43:09 UTC
I can confirm that the bug is still reproducible. The important point is to create the frame explicitly, not use auto-keyframing of the transform tool
