Description postix 2025-12-27 19:56:44 UTC 
STEPS TO REPRODUCE
1. Have a folder with 24 Mega pixels images from your camera on a SSD
2. Open a JPG from the folder in Gwenview

OBSERVED RESULT
Gwenview opens and shows the JPG immediately, but slows down extremely as it keeps loading more previews for the thumbail bar for > 10 seconds.

EXPECTED RESULT
Gwenview keeps being usable.
