Wrong Alignment of Menu Items under GTK3

Type             : Bug
Priority         : Medium
Gambas version   : 3.20
Product          : GTK+3 component


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

Hi
I am developing a huge application and at some point I noticed that the alignment of the menu items are wrong (shifted to right).
So I boiled the application down to a minimum and finally found, that this happens when using gb.gui. After I changed to gb.gui.qt the problem was gone.
The wrong alignment also occurs in the menu of a MenuButton.

Since I have to stick to GTK for several reasons I would be pleased if this bug could be fixed.

I attached two screenshots and the according minimum demo app.

Best regards
Claus
