Description ent3rm4n 2024-10-06 14:47:01 UTC

The editing tool can race when editing while saving an image.


STEPS TO REPRODUCE
1. Take a sufficiently large enough image (sorry, don't have a sample right now)
2. Rotate it with the editing tool, then click save on the "Current image modified" bar
3. While it is getting saved, use the crop tool to crop it

OBSERVED RESULT
No "Current image modified" bar appear after crop; gwenview can be closed while not saving the latest change (cropping), without prompt to save the changes. The crop is not reflected in the saved file.

EXPECTED RESULT
Notice to save the image again after cropping.

Still replicable in 25.08.0. Here are more exact steps:
Download a big image, like https://upload.wikimedia.org/wikipedia/commons/5/56/Flying_Squirrel_Fractal_27062019.jpg

1. Rotate the image but do not save yet.
2. Click on crop and drag the crop area to somewhere smaller, but do no click on the "crop" button yet.
3. Click on "save", while the gear icon is being animated (meaning processing), quickly click on "crop".
4. Gwenview reports the file as saved, but in fact the crop isn't saved.
