Created attachment 134617 [details] About box build with enable-kde4 on LXQt with Breeze Dark theme The font color in the About dialog is not chosen from the system default. That's not a problem for black on white themes but in case of inverted colors the text is not readable. Please use always system default. If necessary highlight parts with bold style or increase size.
