Agreed, the problem is not in nheko use of Qt, but elsewhere in the
system imposing a different use of Qt, which is broken: The imposed
style evidently lacks support for all uses of Qt, which means it is
broken to impose that style globally on the system.

If mobile-tweaks-common is in Debian, then please do file a bugreport
against that package.

No, the root cause is not nheko: Nheko works fine when an only partly
supported Qt style is not imposed globally on the system it runs on.
It is not a bug in nheko to use Qt6 out of sync of KDE.

Please move the discussion about other parts of the system to those
parts of the system - e.g. KDE discussions are irrelevant for nheko, as
is globally-for-mobile-setup.

No need for apology - until it was clarified where the cause of this bug
was, it was appropriate to track it as tied to nheko.
