Description Rafael Linux User 2024-02-05 20:51:02 UTC 
SUMMARY
I have 2025 JXL files in a folder. When I open it with Gwenview, it begin to show thumbnails, while literally eating all my RAM till I have no more (I have 16GB RAM).


STEPS TO REPRODUCE
1. Create a directory with JXL images (HD resolution mostly)
2. Open previous folder with Gwenview

OBSERVED RESULT
While generating thumbnails, Gwenview eats all RAM slowly, till system need to take swap storage and then system begin unresponsive. 

EXPECTED RESULT
To show thumbnails without issues.
