I was able to reproduce this in a Hyper-V VM, and on a physical machine with an nVidia video card, so it appears generally reproducible on multiple machines.

I just created a brand new user with zero user-home-directory-customization logged in, clicked on Konsole, and typed geany, and the issue reproduces, so no user-specific home directory prior states appear to be required.

Issue reproduces on icewm and Plasma,  and not on gnome.

Screenshot of the same system, where these gtk apps work fine on Gnome desktop.

No, it isn't.
It uses GTK3.

And this is a Known problem:
GTK 3.20 broke compatibility with themes for older versions.
In particular, KDE's breeze theme for GTK3 has not been updated yet, and does not fully work in Tumbleweed at the moment.

For now, please set a different GTK3 theme in Configure Desktop->Application Appearance->GTK, e.g. Adwaita, to "fix" the problem.

Same issue. The Bauer's trick works fine.

But for portuguese locale, I think is better to describe how to arrive to the configuration:

"Configurações do sistema" -> "Aparência" -> "Estilo dos aplicativos" -> "Estilo dos aplicativos GNOME (GTK)" -> "Selecione um tema do GTK3"

Change to "Adwaita".
