Maybe someone here can give me an answer for my "issue". I'm working under Archlinux with Xfce desktop and I'm using a dark theme ("Nordic"). And with that theme, Calibre doesn't show the background color of its labels. Maybe the following screenshot can explain better the thing than the words:
The text of the label is white and the background should be more or less brown (according to the Nordic theme), but it's displayed as white, so the text can't be viewed. The color for background labels is ok with the theme because any other program shows the background correctly (for example you can watch here a screenshot of FeatherPad, a Qt6 program):
When I enable the native dark theme of Calibre all is showed as expected:
I'd like to know if there is any way to modify the background color of labels in Calibre so that all looks perfect with the Nordic theme.
Many thanks in advance for any info you can give me about this "issue".
