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)

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

To show thumbnails without issues.
