    Phoronix: Intel Developer Working On Adding HDR Display Support To Wayland / Weston

    While the Linux desktop's display stack has largely reached parity with Windows and macOS in recent years (most recently, the DRM core properties hitting Linux 5.0 around Adaptive-Sync / VRR), but one of the areas that has remained elusive has been for full HDR display support. We've seen NVIDIA working on nursing the X.Org-based display stack for HDR while now Intel appears to be working on the necessary Wayland changes...

    Traditional color management isn't really relevant when doing HDR in any case -- plus, we're already used to doing all color management internally, since it's a mess in X11, too.
    Right, but (by design I'm told), the application doesn't know which output it's pixels are going to end up on, so it can't do the appropriate color conversion.

    Except that due to the design of wayland an application can't know which monitor they are running on (making automatically selecting the right output profile impossible) and wayland doesn't have a way to actually calibrate nor profile the screen. So in essence wayland is worse then X11 currently is. Add to this that large gamut/HDR screens are becoming mainstream making full-screen color management a necessity (otherwise a lot of people are going to complain that they favorite app/video/game/etc looks wonky), provided this is implemented correctly this shouldn't be a problem (see MacOS) but if it isn't graphics artist need to turn this off (hopefully with a runtime option) in the best case or are stuck on X11 for the worst case.

    Before getting too exited, take a look at the (total lack) of Color Management support in Wayland. Maybe it's not such a good fit for Krita until Wayland developers wake up and notice that they've missed something...

    YAY! We've been working on HDR support in Krita since mid 2018 -- and have it working on Windows, and on Windows only.

    They're light years behind OS X.

    no, intel is an author of wayland protocol specification
