Windows 10 (msys2) current Gtk3 dual monitor gtk_window_get_position + gtk_window_move and the window disappears
I'm attaching few lines of code to reproduce the bug, building with current gtk3 on Windows 10 (msys2)
Basically if you have dual monitor where one extends the other, if you gtk_window_get_position you get (x, y) then you gtk_window_move to the (x, y) just retrieved and the windows should not move, but it goes away.
This affects my gtkmm3 application on windows https://github.com/giuspen/cherrytree/issues/1943
