Ok, I'm not sure if this is our bug or not, but it appears to be a bad interaction between the GtkTextView widget we use packed inside a GtkScrollWindow widget, with Ubuntu's expanded "overlay scrollbar" feature.
It seems like we don't get a minimum height allocation when the overlay scrollbar is in use, despite the button widget along side our text entry taking up a certain height.
It is true that we don't specify a minimum height for that widget though - and that could well be the underlying problem.
For now, you can work around the issue by starting gschem from the command prompt with:
