Yes, I only just realised this recently. But why call an icon set a
Theme when it is clearly not a theme. I would respectfully suggest that
Claws be modified to reflect the word "icon set" not Theme as it is now.

Yes, as you say Claws Mail uses GTK+ 2.24.32 / GLib 2.64.3 , yet the
behavoiur that I experienced didn't reflect those 'rules' in totality.

When I used the Application Style function and set the theme for GTK2
to the Adwaita theme, Claws still exhibited the problem. It was only
after I also set the Application Style for GTK3 also, that the
problem/bug disappaered in Claws. And yes, I did exit/enter again in
Claws just to make sure.

So, the rule of "GTK 3 themes only affect GTK 3 applications" is not
correct, a GTK3 theme clearly affected a GTK2 application. But of couse
that could be due to all the multitude of layers, KDE, Plasma, themes,
etc,etc.

The first sentence is correct, as the Claws 'themes' are icon sets. The
second sentence, I have proved, was not my experience.

Given that I have never had to touch any theme, colors, fonts, video
drivers in Kubuntu/KDE, (everything worked out of the box), I feel it
is safe to assume at this stage, that it is most that KDE has a big
part to play in this.

Thanks muchly for your help,
