Description Ahab Greybeard 2022-04-01 09:31:44 UTC

SUMMARY
This bug is present in versions 4.4.8, 5.0.2 and the Mar 31 5.1.0-prealpha (git 625152f808) appimages, tested on Debian 10.

A vector layer can have opacity keyframes added to it and these work when the animation is played.

When the document is Saved as a .kra file, Closed and then Opened, the opacity keyframes are not present and the opacity of the vector layer has been set to whatever the animation frame opacity was when it was Saved.

STEPS TO REPRODUCE
See Summary

OBSERVED RESULT
See Summary. This is to be expected.
This situation has confused at least one user in the recent past.

EXPECTED RESULT
It should not be possible to add opacity keyframes to a vector layer.

Note: The workaround for this is to put the vector layer in a Group and apply the opacity keyframes to the group layer.
