Description Jim Jones 2022-04-22 07:52:13 UTC

SUMMARY
when gwenview is used to show folders with hundreds/thousands of files the time to create a preview of files can take a long time. If the user scrolls down to pictures without an existing preview, gwenview should not create previews in a linear way and should instead prioritize the creation of preview for the pictures that are currently in "focus"


STEPS TO REPRODUCE
1. open folder with massive amounts of pictures
2. scroll down some pages
3. wait for a long time until the preview of the focused pictures is created

OBSERVED RESULT
wait for a long time until the preview of the focused pictures is created, when the user scrolls down


EXPECTED RESULT
the preview of the focused pictures is created instantly, when the user scrolls down

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.24.4

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Gwenview 25.08.0 (the latest released version)?
