I have a complex UI where a Grid is inside a Grid, inside a Grid, etc. (GTKmm 3.24.20)
The problem is two identical buttons, but for some reason they have a different size:
Left button is inside Grid/Grid/Grid, where right Button is inside Grid/Grid.
Grid margins is set to 0:
If I change the container from
Gtk::Box then the buttons are the same size.
Any ideas what could be wrong here?
