I filed the following bug: https://gitlab.gnome.org/GNOME/gtksourceview/issues/41, which promptly got close as "expected behavior". Apparently, you'd either have to use CSS or install a new font map for the GtkSourceMap. Sure is disappointingly helpful. I can't figure out the connection

Forgive me for second guessing you, but are you definite that that your loop is better/easier to maintain than a Gtk main loop? So far, if I was tempted to implement my own main loop, it wasn't because the Gtk main loop was inferior, but because I was looking at it the wrong way. Definitely

Thanks for the suggestion. Believe it or not, I had just arrived at that same solution! I first tried to use GLib.timeout_add(), and that worked too, if the time was larger than 300 - 400 ms, which is on the verge of annoying. I then tried idle_add(), and I guess that makes the 300-400ms

If it's only for reordering the elements in the tree view, you can use the built-in Gtk.TreeView.set_reorderable() method [1], and you're all set. You get inserted/deleted signals for moved rows so you can know when and how things changed if needed, and the underlying model is also changing

I have had very similar experiences with liststore.clear() in Python3.5 and Mint 18. To work around this I do: store = treeview.get_model() #may not be necessary in your code treeview.set_model(None) store.clear() store.append('my string or etc') treeview.set_model(store) This works.
