In my report I made a typo, this is what I said: "Do not cache thumbnails above this size:"
That should actually read: "Do not cache thumbnails below this size:" I have since gathered some more data and found numerous reports of this, and one user seems to have found the commit that caused it: https://github.com/lxde/libfm/commit/00120b795a811ae70db89dde5021461658f2880f I have since made myself a band-aid consisting of a python script that runs once after bootup and properly caches all thumbnails over a given size, with a menu entry to run it during session if a lot of image files are added. But it is a band-aid, not a fix. I had intended to fix it myself, but then the GTK3 version came out and I think it would be smarter for me to try and patch that version. I understand what they were trying to do and there is some merit in it, at least for edge cases, but the implementation was wrong. ~greenjeans Sent with [Proton Mail](https://proton.me/mail/home) secure email.
