Before we received new gamma updates via D-Bus and posted the update to KMS directly. This won't be possible with atomic KMS, since one can only update the state of a CRTC once per cycle. Thus, to handle this, when configured by D-Bus, only cache the value, and mark it as invalid. The next frame, the native renderer will pick up the newly cached gamma value and configure the CRTCs accordingly. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1488>
