[Bug 1916857] [NEW] Color corections not sticking in Plasma

[Owen]

Public bug reported:

My laptop screen needs colour corrections. In Groovy this worked but in
Hirsute it doesn't.

I calibrated the screen and have a good profile. In Groovy I used the
systemsettings5 app to install and use this colour correction. All
worked perfectly.

In Hirsute this profile is still there and clicking on it applies the
corrections, but a few seconds later it reverts. The checkbox remains
where it is. Clicking in Default and back on the profile repeats,
profile on, profile off after a couple of seconds.

I have installed three other profiles and notice that the delay is after
the first click. I.e. clicking on profile after profile, the reversion
always occurs about 3 seconds after the first click, not the last.

To get the profile to stick I had to log out, log in using Ubuntu /
Gnome default desktop, apply the corrections there, log out and log in
to Plasma-X11. However, this didn't last over a reboot.
