Hello, i'm still using ``geany 1.37.1 (built on 2022-10-03 with GTK 2.24.33, GLib 2.66.8)``
The only reason for this is the filetree sidebar, that don't align correct not because geany's code but cause gtk3. I also issue this #https://github.com/geany/geany/issues/2436 in the past.
The reason, i issue again for the same reason is the a new build i made to email client ``Claws Mail`` version 4.x that also use gtk3, while version 3.x using gtk2. Seems that these uys there find a way to come around this. Not an expert in gtk, so not really sure if the same widget.
I post 2 images here, one with the side bar wide enough, and one with the side to minimal width.
