is just a wayland is broken thing I think gambas is missing a trick.
I mean, I can load gnome files or gnome text editor and they open at the
last opened position not just 0,0 .
they seem to know and remembrer their screen position jut fine.

So I think it's a gambas problem/misconception as it seems like only my
gambas apps that have zero control over window positioning on the screen.
