Krusader is, most of the time, unresponsive on Plasma 6

Kursader 2.8.1 and Krusader 2.9.0 (unstable) version on Plasma 6, EndeavourOS, Intel GPU, both have been (most of the time) very slow to start or changing directory. But sometimes, I don’t have problem at all.

I run in debug mode krusader -d but don’t find anything abnormal (no error message).

Problem description:

  • Delete the configuration of krusader

  • Start krusader

  • It may take about 10 or more seconds to start or changing the location.
    It’s hard for me to explain, so I describe by examples:
    (arrow direction means the location is change from -> to)

    • //usr/ [no problem]
    • //dev [slow]
    • //run [slow]
    • //home [slow]

But, when ever I enter one of those directories, browsing inside those directories is normal.

Sometimes, it’s slow enough that the krusader window turn gray

I run a live Plasma 5 distro, and run krusader, and don’t have any problem.

Dolphin also doesn’t have any problem (and fast).

Here is the log when I run journalctl -r, from when I started krusader, and then the problem occurred.
