Slowdown on displaying large directories between thunar 4.21.1 and 4.21.2

Version information

Thunar 4.21.2 and 4.21.3

Ubuntu 24.04.3 with Xfce 4.18

Steps to reproduce

  1. ...Launch a single thunar (v4.21.2 or v4.21.3) window and view (list, icon or compact) a directory with 35,000 subdirectories

Current behavior

On a local NVME disk, it takes 18 seconds to render the view. Doing a Ctrl-R refresh takes 50 seconds.

Expected outcome

thunar v4.21.1 only takes 3 seconds to render the same heavily populated directory.

Additional information

Show thumbnails set to never.

Takes 70%-100% of a single CPU core while rendering.

Not sure if this is connected with #1723 or #1315 (closed)
