Nemo is not listing all contents of directory

Distribution

Package version

nemo 6.0.2

Frequency

Rarely

Bug description

My download folder is not displaying all the files. It's not because they are hidden but some other issue. See screen shot below showing files listed from the terminal and files listed in the download folder with nemo.

Here are screen shots of the individual windows:

Nemo:

Terminal:

E.g. the file 12004930900000081.pdf is not visible in nemo.

Steps to reproduce

Not sure how to reproduce it. It started happening yesterday 2024-12-12 GMT+1. Downloading files from firefox and then opening the download folder wouldn't display the files.
Also, if I copy a file using terminal to the download directory, it does not appear in nemo.

Expected behavior

When a file is downloaded into the ~/Download folder, it would be shown in the download folder in nemo.
When I copy a file into a folder, using the terminal, it should be visible in nemo when opening that folder.

Additional information

Restarting nemo by executing nemo -q from terminal is a workaround for the issue.

Start by reproducing the missing-file behavior in Nemo 6.0.2 on Linux Mint 21.3, comparing files copied or downloaded into ~/Download with the terminal listing. Check whether restarting Nemo with nemo -q restores the display, and use that as the observable baseline. Done means newly created or copied files consistently appear without restarting Nemo.
