'gb.gtk' is the GTK+2 component, you didn't remove it, so it's normal 
you still get it.

Apparently there is something in the QT5 version of Ubuntu 18.04 LTS 
that breaks the QT5 component on Gambas 3.17.

The QT4 and QT5 components almost share the same code, at least for text 
rendering.

As for the flickering, I would say that XFCE is in cause more than 
GTK+3, but who knows. You can check that by changing the window manager 
(with composition enabled, without...). At least I have no idea how it 
could be Gambas' fault.

To know exactly what happens, you must be more precise, by explaining 
each problem clearly, and testing them separately.

For the IDE crash while debugging, it's almost sure that it's a bug in 
Gambas. But then you must give me a project that allows me to reproduce 
it so, or at least describe what you did exactly, so that I could fix it.
