Description Antti Savolainen 2024-10-19 02:15:51 UTC
SUMMARY
Demonstrative video: https://youtu.be/Qb7yWsdXPyU
At seemingly random, the filepicker sometimes doesn't load the thumbnails. It seems to be affected by the amount of files a folder contains as I wasn't able to repro this in a folder that contains just a few images. The thumbnails load after hovering over them with a mouse. 

STEPS TO REPRODUCE
1. Open the filepicker in a folder with a lot of images

OBSERVED RESULT
Some of the thumbnails do not load

EXPECTED RESULT
All of the thumbnails should load

file picker not showing thumbnails

Attachment is from a folder I had opened 3+ times in the file picker and those thumbnails (images at top of folder) at not shown.  It seems like the file picker is (1) having some glitch with the thumbnail cache (2) trying to regenerate thumbnails every time.

This glitch happens on a regular basis.

I am also using an Arch based distro.
