Description MarcP 2020-01-08 11:56:19 UTC 
SUMMARY

This is just a minor cosmetic issue, but I thought of reporting it anyway. In the People panel, if you go to the Unknown section and select several faces and tag them with a name, the progress bar on the bottom will start at 100% and end at 0%. Everything still works just fine, it's just that the progress bar goes backwards.

STEPS TO REPRODUCE
1. Select several faces from the Unknown category in People.
2. Tag them with a name.
3. Observe progress bar.

OBSERVED RESULT
Goes from 100 to 0.

EXPECTED RESULT
Goes from 0 to 100.

SOFTWARE/OS VERSIONS
digikam-7.0.0-beta2-20200105T130918-x86-64.appimage in Ubuntu 18.04LTS with Unity.

If you open the progress manager, you will see that there are 2 processes in quick succession. The first jumps to 100, then the second starts at 0. In the overall display it looks as if it is going backwards.

Aha. It could be what you say. What I usually see, is a bar for each tagged image, and the one on top being the one that appears to go backwards.

Hi Marc and happy new year,

Can you reproduce the problem with the appimage bundle 7.5.0 pre-release available here :

Thanks in advance

Hi Gilles, happy new year to you too. I have seen this behavior recently, but let me try the last appimage during these days and I'll confirm it.
Comment 5 MarcP 2022-11-30 21:17:54 UTC 
Hi. Just to confirm this still happens in the 8.0.0 preview appimage. I have tagged lots of faces these days, and the progress bar goes backwards. Apparently it's just for faces, for normal tags, it goes from 0 to 100%.
