Description IT-KB 2025-11-24 14:46:15 UTC
Slideshow (Set to "A-Z") restarts from first picture after reboot/shutdown or logout. From my understanding it should remember the last shown picture and continue from there.
Comment 1 IT-KB 2025-11-26 10:33:02 UTC
this did not happen on plasma 6.3.6 and 6.4.5

STEPS TO REPRODUCE
1. Select Folder trough GUI to run as slideshow (A-Z)
2. Select "Next Wallaper" from desktop or wait.
3. restart/logoff
4. Slideshow starts from first picture in selected folder

OBSERVED RESULT
Slideshow restarts at first picture of selected folder

EXPECTED RESULT
Slideshow should show the last picture shown, before logoff/shutdow/restart

I can confirm the behavior for sorting order "A to Z" and also for "Z to A", "Date modified (newest first)", and "Date modified (oldest first)".
In addition to the behavior occuring on restart and logoff, it also happens after the screen was locked and the displays turned off for a while (due to powersaving options).
