THE BUGS
When using Wayland, Redshift does not change colors according to color profiles. Under X11, this does work.

As far as I and have been told, Wayland/Weston does not currently have an API for changing these sorts of settings in user space.

EXPECTED
The screen is expected to become more "reddish" as time changes throughout the day/night to relieve eye strain.

BACKGROUND
Some background for those not familiar with redshift:

OTHER
This is a deal breaker for using Wayland for people such as myself.

You're probably not going to like the answer, but regardless: this has to be implemented by every compositor individually. Wayland does not (and will not) provide a generic facility for arbitrary clients to capture and rewrite screen content.

You should chase this up with your desktop environment of choice.
