Reproducible: Always Opacity keyframes are lost after a save/load roundtrip. Steps to Reproduce: 1. Create a new document 2. Add an animation with two opacity keyframes 3. Save and close document 4. Close Krita (bug 374381 will occur otherwise) 5. Reopen document There are no more opacity keyframes.
Aaargh... I cannot believe that nobody noticed this!
Looks like this broke when we made Krita save a copy of the image instead of the original image.
This is fixed in master with the new async saving, just checked :) I am closing this then. If you can still reproduce this bug in 4.0/master, please do not hesitate to reopen it!
