SUMMARY
Dolphin is stuck in light (aka flashbang) mode. changing themes fro me the commandline or the kde system settigns does nothing (changing icon themes and window decoration themes works).

STEPS TO REPRODUCE
1. update dolphin to 24.08.3 with KDE Manjaro
2. open dolphin

OBSERVED RESULT
Dolphin is stuck in light mode.

When run from command line get the error message: kf.config.core: Watching absolute paths is not supported "/usr/share/color-schemes/BreezeLight.colors"

EXPECTED RESULT
dolphin should respect theme set from cmd or settings menu

SOFTWARE/OS VERSIONS

Qt Version: 6.8.0
Kernel Version: 6.6.63-1-MANJARO (64-bit)

ADDITIONAL INFORMATION
I have qt6ct installed with $QT_QPA_PLATFORMTHEME but disabling it doesn't do anything.

I've also tried $QT_STYLE_OVERRIDE but that does nothing

dolphin --platformtheme also does nothing.

I've used kfind to search as many files as possible (name and contents) looking for a config file that explicitly has the absolute path but can't find anything.

the error message specifically comes from https://github.com/KDE/kconfig/blame/master/src/core/kconfigwatcher.cpp but I'm not much of a programmer so I don't know where to go from there.

Rant: This could very well be a Manjaro specific issue. I'm so done with their jank but too lazy to just switch to plain Arch.

Hi - Arch/Manjaro seem to not follow one of the KDE Plasma packaging recommendations, which is to have qt6ct conflict in the package manager with plasma-integration to prevent both from being installed at the same time.

Does this bug reproduce if you uninstall qt6ct, make sure plasma-integration is installed, and test on a freshly created user account?

Thanks!

Hello!
I am also experiencing this issue on Arch with Hyprland/i3 and it seems like KDE apps ignore the theme overrides from "QT_STYLE_OVERRIDE=my_theme" and "QT_QPA_PLATFORMTHEME=qt6ct".

Running plain QT apps applies my defined theme just fine, but KDE apps just pick BreezeLight anyways. In Kate one can change the theme in the program and it keeps that setting. Dolphin for example doesnt have an option to change the theme, so its stuck on the light theme. 

If there is anything else I can provide to resolve this issue?
Since you mentioned plasma-integration is this responsible for picking themes when installed?

Thanks in advance!

Hi - I could be wrong, but I believe that would be a separate issue - this one is around how colors appear when run within the Plasma environment, while what you're describing sounds more like https://bugs.kde.org/show_bug.cgi?id=493384 , which concerns how colors appear when run outside of Plasma.
