Description Ralf Habacker 2025-04-16 21:29:07 UTC 
SUMMARY
Without this, white text is shown on white background when a dark color
scheme is used, because the text follows the color scheme but the background
remains white.


STEPS TO REPRODUCE
1. build umbrello from git source on Linux
2. On a KDE desktop setup using dark theme
3. start umbrello

OBSERVED RESULT
The background of the diagram window is white and not black as expected.
