GNOME 50 Lands Updated Wayland Color Management v2 Support

Written by Michael Larabel in GNOME on 20 February 2026 at 09:21 AM EST. 37 Comments
Following GNOME 50's Mutter merging sdr-native color mode support for wide color gamut displays this week, another late addition to Mutter has now been merged ahead of next month's GNOME 50 stable release.

The late change merged today to Mutter Git is supporting the Wayland color management v2 protocol. Mutter already was supporting the initial color management protocol but now is updated to include the latest adjustments to it found in the upstream Wayland Protocols spec.

There are various minor changes with the v2 bump, including sRGB piece-wise TF, making use of 64-bit IDs to avoid potentially recycling the IDS otherwise, some event changes, and other minor alterations. Nothing too exciting but simply Mutter being punctual in following the latest upstream Wayland changes.

More details for those interested via this merge request that landed in Git earlier today in making it for GNOME 50. Following the merge, it was noted that the new code does cause Mozilla Thunderbird to crash but doesn't happen with Firefox. That will hopefully be fixed up in time for next month's stable release.
