Distribution

Mint 22

Package version

6.2.6

Frequency

Always

Bug description

When I open a folder that contains hundreds or thousands of photos, my computer freezes while the thumbnails are displaying.
The first time thumbnail directory contains hundreds of photos, the system remains frozen and the mouse or keyboard does not respond.
I tested with 2 PC desktop and with different SATA SSD and M.2 SSD and got the same error.

Steps to reproduce

1. open a folder that contains hundreds or thousands of photos (open it first time with no thumbnail cache)
2. quickly slide vertical slide bar to load as much as photo to thumbnail cache
3. Your PC Freeze, the mouse and keyboard does not respond, whole system crash.

Expected behavior

Even Nemo crush, it should not freeze the PC. The mouse or keyboard should respond and keep Linux running.

Stop thumbnail can solve the problem, and the system will not crash or freeze. I use Dolphin now as the mouse and keyboard never get freeze in same condition. I recommend everyone to switch to other file management tools or use other way get a preview of photos folder.

Xfce 's Thunar is also a good choice. Before Nemo fix I recommend Thunar.
