Attachments: Screenshot showing default Oxygen Style with mostly dark widgets, but hard-to-read Process Table

Description Marco Parillo 2025-07-04 19:00:36 UTC 
SUMMARY

Text of Process Table is very light gray against a white background


STEPS TO REPRODUCE
1. Add System Monitor Sensor Widget
2. Select Display Style: Process Table
3. Switch Global Theme to Oxygen
4. Reboot
5. Observe the widget.

OBSERVED RESULT

Text of Process Table is very light gray against a white background

EXPECTED RESULT

Text of Process Table should probably be white against a dark background (matching other System Monitor Sensor Widgets as well as the Weather Widget under Oxygen), but any readable result would be an improvement.

The same applies to the Application Table.
Comment 3 Marco Parillo 2025-07-05 15:15:25 UTC 
Is it likely that I picked the wrong product, and I should have picked Oxygen? If so, which component would be best?
Comment 4 Filip Fila 2026-02-13 08:48:45 UTC 
I can also confirm this. The color scheme seems to have no effect. This is an an issue with the how the Plasma theme's colors and this widget interact. 

The widget is loading a 'View' color group, which although seems technically correct in this case means a white background. For coherence with other widgets I'd also prefer it to load a dark background so as to not have a bunch of white stuff in an overwhelmingly dark theme. I'll play around with the .colors file of Oxygen, see how it affects other places and then submit a patch.
