Description Freya Lupen 2023-04-17 03:53:17 UTC

SUMMARY
When an image greater than the 100th one is selected and the thumbbar is reloaded, for instance by tagging the image, the thumbbar scrolls to show the 100th image as the last one.

STEPS TO REPRODUCE
1. Open an album with more than 100 images.
2. Go to Preview view, enable Thumbbar. Select an image greater than the 100th one.
3. Cause the thumbbar to reload, for instance by resizing it or applying a tag to the image.

OBSERVED RESULT
The thumbbar scrolls so that the 100th image is the last one shown.

EXPECTED RESULT
The thumbbar should keep the selected image visible.

SOFTWARE/OS VERSIONS
digiKam 8.0.0

ADDITIONAL INFORMATION
This is just a guess, but perhaps it has something to do with https://invent.kde.org/graphics/digikam/-/commit/78b3bb6f62633c220d49c4797c7876ed8af7616b ?

Comment 1 caulier.gilles 2023-04-19 04:48:10 UTC

Did you use Linux ? Which kind of database ? Did you use AppImage bundle ? Which operating system exactly ?

Comment 2 Freya Lupen 2023-04-19 13:06:31 UTC

This happens on Windows 10 and with the Linux Appimage on Ubuntu 22.04. Database is SQLite.
