kicad_change_label_popup_slow
Hi, the version info of KiCad is below, and I’m use XFCE4 as desktop.
Kicad start is very fast, but when I try to edit label of ‘net name’ or ‘reference’ or ‘value’, the dialog pop out is quite slow, about 3 seconds. Is it normal?

If you only see this in dialogs with font picker drop downs, it’s a known issue with the GTK font picker widget where the time for the widget to build the list of fonts is quadratic in the number of fonts you have installed, every time a dialog with that widget is used.

The devs are trying to work around the issue. There’s an issue tracking it on gitlab.

Thanks for your reply. it seems is something with the font loading. If I change the name of pin in symbol editor, the dialog pop out is fast.
