Antonio OREFICE reported a new bug.

Summary
-------

sub-pixel antialiasing is ignored by qt4 editor component

Type             : Bug
Priority         : Medium
Gambas version   : 3.8
Product          : GUI components


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

I don't think there is the need to post any code.
Right in the main ide is clear that it is not using sub-pixel AA.
The rest of the gui is fine.
As a side note, i noticed that it works if i open the gui via ssh -Y, even if i connect to localhost!

gtk editor component is displayed correctly.
