Bruce STEERS reported a new bug.

Summary
-------

GTK3 Transparency problem

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : GTK+3 component


Description
-----------

To follow is a trayicon workspace switcher i am working on.

it is made to pop up at lower screen (if trayicon is at the bottom of screen)

seems to pop open in the correct place on qt and gtk3 if window is not transparent

But i cannot set the FChooser.Transparent to True on GTK3, if i do the window size and position goes wrong.
