KDE Connect cannnot load the system theme / does not respect dark theming, mesa zink error

[TraceyC77]

Summary

This was originally reported in the forums

KDE Connect does not properly load the system theme in Budgie

Steps to reproduce

1. Set Budgie to a dark theme
2. Launch KDE Connect

Expected result

KDE Connect uses the system theme

Actual result

KDE Connect has a light theme partially or completely

On my test VM, it was completely light. For the user in the forum thread, it was mixed.

Environment

• [X] Is system up to date?

Repo

Shannon (stable)

Desktop Environment

Budgie

System details

Budgie VM In Desktop Settings > Style Widgets: Materia Icons: Papirus Cursors: breeze_cursors Dark theme: toggled on Built-in theme: toggled off

I also observed that Budge Control Center also appears with a light theme. This is not affected by toggling built-in theme on and restarting the app.

Other comments

Running kdeconnect-app from terminal reveals its having trouble reading the theme file I see this in the terminal regardless of which widget style I choose.

At Joey's suggestion I installed kirigami-addons and restarted the app. Same error in terminal and UI still has its default light theme.

Note: for the user in the forum thread, this results in white text on a white background in the SMS window.

The problem is exactly the same in Xfce
