    GTK Making Progress On HDR & Supporting More Color Spaces

    Phoronix: GTK Making Progress On HDR & Supporting More Color Spaces

    Colors within the GTK toolkit have been represented to date using sRGB but developers have been working on supporting other color spaces like Display-P3 and BT.2100-PQ as they work to better support High Dynamic Range (HDR) displays on the Linux desktop...

    How is the fractional scaling support coming along?

    Does gtk still not acknowledge that screens above 1080p exist?

      What's the problem exactly? I've been using XFCE and Gnome (GTK 2, 3, 4) for something like 15 years. Have both 1440p and 4k displays. Seems to work just fine.

        I don't know, I never tried GNOME on 1440p or 4K screen but I think he means something like maybe you can only scale the size by doubling like 2x and 4x but not by fractional units like 1.3 size bigger.
        Or maybe that the font scales but not the UI or the icons or vice versa or something.

          Dear anti-GNOME troll,

          I am writing to let you know that fractional scaling has been working for ages.

            It does work. But GNOME has hidden it behind some experimental setting. I'm using it for some time.

              Also those experimental settings may work only for Wayland, which can be a limitation for some users (e.g. remote desktop on Wayland is limited to the one in the DE and the one in GNOME is buggy). On Fedora the support for X11 was removed already (works in Ubuntu though). The other problem I found is it doesn't offer the options unless your display is an exact resolution of a physical monitor. I would like to use it also in a smaller window of a virtual machine (e.g. to see the taskbar of both the Host and Guest).

                cool, so what are the problems with it?
                Any timeline on when it stops being experimental?

                This is really embarrassing for GNOME and gtk, because everybody else has it already.
                Qt6 has it for over two years now in stable. GTK got it in stable afaik this year (4.14) and GNOME says that this implementation is unstable and experimental.

                  Don't ask me, ask the GNOME devs. Most likely X11 limitations, as the experience would be different across different applications. I.e. X11 apps tend to be blurry.

                    All of my apps I use are blurry. It has not been working for ages on my 32" 4K display, a very common 4K monitor display size that requires 150% scaling to be usable.

                    It only is working for *native* applications, which is not the majority of apps people actually use. Chrome, Discord, Slack, Spotify, etc.
