Description beliumgl 2025-02-23 06:39:28 UTC 
SUMMARY
After enabling colorblind correction for testing and then disabling it, resuming from hibernation causes the desktop to display incorrect colors (not matching the enabled/disabled state). Though the "Enable" option remains off, colors stay distorted. Temporarily fixing this requires re-enabling and disabling the setting again.

STEPS TO REPRODUCE
1. Enable colorblind correction.
2. Disable colorblind correction.
3. Hibernate the system.
4. Resume the session.

OBSERVED RESULT
Persistent incorrect color display after resuming.

EXPECTED RESULT
Normal color rendering after resuming from hibernation.

I'm not able to reproduce this with git-master using sleep (this system is not set up to hibernate)
Leaving open for someone who has a system with hibernate to try to reproduce

Do you also experience this with other KWin effects?

I can't currently check this for other KWin effects.

I've also checked what will happen if i hibernate with colorblind correction turned on. The result is colorblind correcting turned off, though Apply button isn't enabled and colorblind correction mark is checked.

Now I'm sure this bug is reproducible with hibernation. First time I got this bug accidentaly, but when I reproduced this bug again, the result still the same.
