Summary
-------

Fedora issue, clicking activated window triggers DeActivated event

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


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

I have a program that pops open a window and i have set the Form_DeActivate event to auto close it.

This works fine on all systems i've tried (Deb, Mint, Manjaro, Suse) except Fedora.

With Fedora33 I have this issue...
gtk2 / gtk3 and qt5 all close the window as soon as i click it (even if already Active)
It's as if it is getting de-focused de-activated.

With qt4 as the program loads the window (that should not be Visible) shows the titlebar and border (no contents) at screen top left.
it cannot be closed by it's button but if i click the trayicon to open the windo the ghost window disappears and it opens as should.

Will attach a clip...
