    Michael something got messed up with the first link, spanning half the article.

    Edit: already fixed.

      GNOME 48 would be perfect with HDR, triple buffering, FIFO (commit timing) and tearing support by demand.

      Daniel has been working pretty hard this whole month with this, so hope it gets merged before feature freeze or at least, make an exception this time if it doesn't arrive this week yet.

        Hey, I don’t care when it’s ready as long as it is fully baked and fully operational when it’s released. My personal hope is it’s ready in time for Ubuntu 26.04 LTS. That should be an attainable milestone and a rather nice upgrade to Ubuntu. Once again though….please don’t release a half assed product that will just degrade anyone’s confidence in Gnome and Ubuntu.

          It would be great to see this finally land. I know it has been in the works for years

            What is the state of HDR on GNOME these days anyways? I haven't been hearing much HDR related Linux news recently. I'm really hoping we can get it sometime soon, but I have no idea how far away it actually is.

              Check Mutter MR/commits, you can enable it on 47.x as a hidden flag but it's not ready yet.

              I think 48 may have it ready, even control center is ready to expose HDR toggle.

                  Triple buffering has still blocking bugs and is unlikely to make it into the Gnome 48 release. However, Ubuntu includes it by default with their other Gnome patches...
                  Use triple buffering if and when the previous frame is running late. This means the next frame will be dispatched on time instead of also starting late. It...

                    Everything is still patchwork on all fronts. A big problem is getting access to HDR-capable displays for testing, which are only now starting to take hold in the consumer and business side of the display market and the capabilities of the displays are patchwork and inconsistent outside of the high-end OLED and miniLED offerings and HDR hasn't caught on in laptop displays yet. There's some concerted-effort on the software/distro side of things, but the hardware side is not collaborative and needs financing/centralized organization and support from the display makers, to get the software what it needs to bring forward more testing.
