It does, and since external displays don't necessary use the same
resolution as the primary one our current approach of
Gdk.Screen.width/height results in a very broken experience.

See

The solution I am using for the Flatpak ports is to force activities to
display only on the primary monitor. I prepared a helper to make these
fixes a bit easier in sugarapp lib.

See https://github.com/tchx84/sugarapp/blob/master/sugarapp/helpers.py#L24

The project is to deploy a set of solutions specific to each activity;
