Description raymond.d.lucas 2020-05-15 12:29:29 UTC 
SUMMARY
In the release candidates after digikam-7.0.0-rc-20200502T111802-x86-64.appimage. Most recently tried is digikam-7.0.0-rc-20200514T150640-x86-64.appimage.

STEPS TO REPRODUCE
1. Open an image in Image Editor
2. Make an edit eg select a section and crop (CTRL+X)
3. Try to undo (CTRL+Z) and 

OBSERVED RESULT
No visible change occurs.
Interestingly when you close the Image Editor (CTRL+W), it does not warn you to save the changed image. It's as though it thinks it has un-done the change and is back to the original, even though that's not reflected on screen.

EXPECTED RESULT
Image returns to it's original state.
