root mode: No toolbar symbols (Manjaro Arch)

[buhtz]

BIT's log output told me to ask here. 🤣

I am using 1.5.3-dev on Manjaro Linux (Arch based). BIT as regular user looks fine. BIT as root (via poolkit) do not show me the icons in the toolbar.

Couldn't find something about this in FAQ or known problems section. Didn't we had this before somehow?

Side question: Why does "running-as-root" in the debug and in the diagnostics output show False?

Maybe related comment #2345 (comment). It is about that BIT checks for "adwaita" but the dir name is "Adwaita". In user mode Qt might be aware of this mistake and correct it by itself, but in root mode it is not.
