Description Iyán M. V. 2024-02-19 16:34:26 UTC 
SUMMARY
The new style do show the screens in the Display Configuration has a beautiful blue grading in the bottom. However, this grading uses the whole area of the screen for certain scale level or for different system settings window's size.

It is hard to explain by words so here is a video of the issue:

STEPS TO REPRODUCE
1. Open System Settings -> Display & Monitor
2. Change the window size
3. Change the scale level

OBSERVED RESULT
The blue grading changes with both the window size and the scale level, even without applying the new settings.

EXPECTED RESULT
Style should remain the same no matter the scale or window size

This looks like some kind of GPU driver glitch, because the blue band on the bottom isn't supposed to be a gradient at all! It looks like a flat color for me with a 10th gen Intel iGPU and 225% scale (on one screen) and 110% scale (on another screen), no matter how I resize the window or further change the scales.

I can't replicate this issue anymore. Don't know if it was fixed in newer versions of mesa, Qt or Plasma.
