I have calibrated my monitors to create icc profiles, they show up in KDE color management and everything used to work exactly as it should. Now every time I start my computer it goes like this:

1. I log in to my account
2. It shows my desktop, with the right colour correction.
3. After a few seconds the colours revert to look un-calibrated on both monitors.
4. I restart the colord service and it loads the colour correction again.

As an alternative to step 4, if I go to KDE colour settings, select the default profile and then back to my profile then it also starts looking good again.

This problem must’ve started a week or two ago, but unfortunately I haven’t been able to pinpoint exactly when. I haven’t touched anything related to colour management in months, and don’t think I’ve done any changes to my system other than upgrading packages.

Can’t see anything colour related in the syslog except colord loading the correct profiles. I removed all the old profiles that I wasn’t using anyway. I removed dispcal’s profile loader from autostart to make sure it wasn’t interfering with something. The profiles are both installed system wide and in my user folder.

Using Fedora 39 KDE.

Anyone have any idea what could be wrong, or even how to debug this?
