Bug description

Colors are oversaturated (especially in screenshots) under the X11 session:

Steps to reproduce

1. Take a "base" screenshot
2. Screenshot that screenshot 2-3 times
3. Notice the color change

Expected behavior

The color should never change (or should only change minimally due to compression), such as in the Wayland session:

Additional information

I originally had this happen to me a month or two ago, but it fixed itself after updating. Only after reinstalling and upgrading to the newest Mint version has this issue re-appeared.

I'm experiencing the same issue, see how the attached screenshots quickly saturate. Even without screenshots this is obvious in some places like highlight colors being purple instead of blue.

Screenshots

Also based on the linux mint community on discord, this seems to be a problem many people are experiencing. This happens regardless of whether or not night light is enabled or active.

Can you run:

killall csd-color
killall csd-color # (it automatically restarts once)

Then attempt to reproduce this? That program manages the night light, but also color profiles, so may still be having some effect.

Without doing that, the problem just... went away on its own?! This is the second time it's done this
EDIT: It's back after a reboot. I can still reproduce it after killing csd-color.
