Mask moves when deleting keyframes

Bug
1

What is your operating system? Windows 10

What is your Shotcut version 21.02.27

Can you repeat the problem? If so, what are the steps?
Repeatable.

  1. Add Mask: Simple Shape to a clip.
  2. Add Horizontal and/or Vertical keyframes.
  3. Delete the keyframes:
    The mask moves to the far left side of the screen and/or to the top of the screen.
  4. Adjust the H & V position even a little and the mask returns to the center.

It could be a known bug, because someone told me he sees the same behavior on his Mac, using an older version of Shotcut.

I always set the 1st frame of the keyframe to a value.

Oui, je peux confirmer que ce bug existait déjà sur les anciennes version (v20.09;27) même si on règle les valeurs de la première valeur.
L’image se décale à horizontal = 0 et vertical = 0 alors que les sliders dans l’UI restent à leurs valeurs.

Yes, I can confirm that this bug already existed on the old versions (v20.09;27) even if you set the values of the first keyframe.
The image shifts to horizontal = 0 and vertical = 0 while the sliders in the UI remain at their values.

Deleting all the keyframes is unexpected. I made a change for the next release that does not allow deleting the last keyframe.
