Bug description

I don't know exactly what causes it, but when it happens, if you right-click a file and move the cursor through the options, the highlight will not show instantly, and instead freeze, taking some seconds to highlight where you are at. If you continue moving, it will take more time to recover up, and you can see in System Monitor the CPU usage skyrocketing.

It seems to not happen instantly, but after some time. Every time it happened I was working with .cbz files, extracting them and managing its image files. If I close Nemo and open it again, the issue don't occur.

Steps to reproduce

  1. Right click a file
  2. Move the cursor through the options
  3. See it

Expected behavior

Do not lag.

Additional information

My hardware specs are Intel Core i5-7400, 24 GB RAM (1x8GB + 1x16GB) and Intel HD 630 (kernel 6.8.0-45) / NVIDIA GeForce GTX 1050 (proprietary, version 550.107.02). The storage drive I was using when the problem occurred was an 7400 rpm Seagate HDD, but it also happened when right-clicking on folders stored on my SSD.

Here's a video I recorded of the issue. It didn't lagged as hard as before, since it recovers quite fast from the freeze. Earlier on, it would take more than five seconds to unfreeze.

Do you have any nemo actions enabled (edit->preferences->plugins->actions)? Their conditions aren't checked until the popup is requested. If there's some complex check happening here it might cause this if it hangs.

If you suspect this, try disabling them all. If the issue goes away, try re-enabling them one-by-one. You should do the same with Extensions (same preferences page).
