slow GUI when using settings search

Posted (edited) · slow GUI when using settings search

The search bar is very slow on my linux system. I always found the search to be slow and i'm wondering if this is normal. I takes over 10 seconds to show all settings again after a search.

I made an strace log for the situation seen in the .gif. 
It doesn't explain where all the time is going but it is rather strange that there are over 28'000 failed file stats.
There are also a lot of repeated file accesses to some .svg files. Seems like unhiding each line repeats the same file operations over and over again. I'm wondering why there needs to be file access at all for just unhiding the settings.

 

Cura version 4.13

    What version of Cura do you use? For me the populating of the settings has gotten a lot snappier with the Cura 5 beta.
