I find if you want wayland compatibility you have to do the following...

Remove any code using Mouse.ScreenX/Mouse.ScreenY
 As gambas reports these values relevant to the Form not the Screen. (like
the form is as top level as it goes) so your code won't work as expected.
Forget any kind of Main Form positioning.
Getting or setting Form.X, Form.Y or using Form.Move() or using Form_Move()
event, all do not work in wayland.
again, like the form is as top level as it can see so it's X and Y are
relevant to itself not the current Screen,
i found Form.X and Form.Y the same (about 20,20) wherever the form was on
the screen.

Sorry i have not tested for the other problems you mentioned about
SkipTaskbar, TrayIcon, etc

Something just seems kinda horribly wrong to me.  but this how it is.
