Thunar sometimes makes my CPU go to 100%. How can I avoid that?

[pirate-parrot]

Hello,

I'm using Sparky Linux 6 Po-Tolo XFCE.
uname -a:
Linux mypc 5.10.0-5-amd64 #1 SMP Debian 5.10.24-1 (2021-03-19) x86_64 G
It's updated.

My question is:
Thunar sometimes makes my CPU go to 100%. How can I avoid that?

Have you checked the Debian BTS for thunar?  I did a quick check, did not see anything. 
https://bugs.debian.org/cgi-bin/pkgreport.cgi?dist=unstable;package=thunar

Did you use htop (or top) to identify Thunar as the culprit or a widget that shows overall CPU usage?

Yes, I did check and it's really Thunar

My guess is this is happening because of thumbnails
But it also happens when I open folders in other partitions
The problem is that I am working with many images also in that same partitions

I have tried (a moment before I write this) to disable some settings in /etc/xdg/tumbler/tumbler.rc
Then I did log out and log in again
And tomorrow I'll see how it goes

However, if someone has some advice, please don't hesitate to reply here

Just a question.
Are you running a script under Thunar the file manager?   If it is not shelling out to a console window it would maybe eat away from the Thunar app resources.

Very good question!

Yes, it is.
I run a lot of thunar custom actions.

However, I notice that the situation I described above happens many times when I use my Directory Menu shortcuts, which I one of my favourite's XFCE panel features.
But, when I do so, I am using Thunar...
