Screenshot showing some of the panels using the wrong theme

SUMMARY
Some panels (left panel, albums panel, etc.) have white background and font after launching the application even if a dark theme is selected. Selecting a different theme solves the issue, but always occurs when relaunching the app (only on dark themes though)

STEPS TO REPRODUCE
1. Select breeze dark theme
2. Close app
3. Launch app

OBSERVED RESULT
Some panels are white

EXPECTED RESULT
Panels follow the selected theme

SOFTWARE/OS VERSIONS
Linux: Linux 6.17.5-arch1-1
Qt Version: 6.10.0

ADDITIONAL INFORMATION
Running on Hyprland 0.51.1

It would appear you're using the Fusion theme, is that right? Or is it some other theme selected using qt6ct?

Had never used qt6ct before, installed it to check and played a bit with the configuration. Yes its Fusion theme and from what Im seeing, these panels that turn white are using the background from the color scheme configured in qt6ct, I had light theme so it used white background, now using a dark theme gives it a dark background

Please don't continue using qt6ct; it will cause other problems. :) I was just asking if you had used it, because it's known to be a source of this problem.

The problem is caused by the app using the Fusion theme instead of the Breeze theme. Are you by any chance using Elisa outside of Plasma?

Oops thanks for the heads up. Yes, I don't use Plasma.
