DESCRIPTION
After upgrading to Plasma 6.7.0, KWin's accessibility color effects no longer
have any visual effect.
This is not limited to the grayscale mode. Other color effects (such as Invert)
also fail to affect the display.
The effects appear to be enabled in System Settings and are loaded by KWin, but
enabling or disabling them produces no visible change.
The same configuration worked correctly before upgrading to Plasma 6.7.0.
STEPS TO REPRODUCE
1. Log into a Wayland session.
2. Open System Settings -> Accessibility.
3. Enable any color effect (e.g. Grayscale or Invert).
OBSERVED RESULT
The effect is enabled, but the display does not change.
No accessibility color effect appears to be applied.
EXPECTED RESULT
The selected color effect should immediately affect the entire desktop.
