After upgrading to Fedora 28, I noticed that Red and Blue colors are inverted on my secondary monitor when using wayland. No problem with the green color. I don't have this issue if I'm using Xorg. Here is a picture with the same image taken on the 2 screens at the same time: image description

Here are some informations about my monitors

I have exactly the same problem. Secondary monitor swaps red & blue while primary monitor is fine. Just upgraded F27 -> F28 an hour ago.

The only solution I found for now is to switch to Xorg, maybe still a little bit early to use wayland :)
