[TTimo]

OS: Linux Manjaro Desktop: KDE plasma, set to dark theme Sourcetrail: set bad_rainbow theme

Observed:

Expected:

• Preference window follows theme
• Can tell the state of the checkboxes

Notes:

If only setting dark theme in KDE, and use Sourcetrail dark or bright themes, the same problem with the checkboxes happens in the main window (for the fatal / errors etc. boxes)
