KF5 5.53.0 upgrade breaks icon themes in Qt5 applications. Downgrading to 5.52 fixes the issue. Changing icon themes in the setting does not solve it. Could be an upstream issue.

Additional info:
kf5 group packages version 5.53


Steps to reproduce:
A simple test is using QtCreator with new KF5. The file icons in the source tree will be fallback Oxygen icons in KF5 5.53 but the selected icon set (Breeze Dark in my case) is used when using 5.52. Also the issue can be observed by building QOwnNotes (https://aur.archlinux.org/packages/qownnotes/).
This task depends upon

What do you mean by "changing icon themes in the setting"? Which DE are you using?

Plasma 5. By settings I mean "System Settings" of Plasma 5. Weirdly it occurs in some subset i.e Project files under QtCreator and QOwnNotes are the problematic ones for me but other Qt apps work perfectly well. I could not reproduce it with my own code too.

It seems like QIcon::themeName() function is somehow started returning empty string.
