GNOME/GTK: OpenGL, WebKitGTK+ 2.18.0, GTK4's Vulkan Support and Icon Size

  • Flickerless Gtk3 OpenGL Transitions

    While I got OpenGL transitions working under Gtk3 at the end of last year basically matching the Gtk2/Generic OpenGL quality the transition into and out of the OpenGL sequence wasn't very satisfying. And with access to HiDPI it was clearly even worse with an unscaled image momentarily appearing before the correct one.

  • LibreOffice Gets Flicker-Free OpenGL Transitions

    Last year McNamara got GTK3 OpenGL transitions working, but it was less than perfect. But now he's managed to provide flicker-less GTK3 OpenGL transitions after landing some improvements into LibreOffice Git.

  • WebKitGTK+ 2.18.0 released!
  • WebKitGTK+ 2.18.0 Brings WebDriver Support, Remote Inspector & Kinetic Scrolling

    The WebDriver support is interesting and allows easily automating/scripting interactions with the browser. WebDriver is just geared for WebKit-based browsers. Details on the WebDriver WebKitGTK+ support via this blog post. When time magically allows I would like to investigate the feasibility of using it for some automated browser benchmarks.

    On the developer front the WebCrypto API is now enabled by default. Additionally, there are APIs to allow overriding the popup menu of select elements and to create a WebKitContextMenuItem from a GAction.

  • GTK4's Vulkan Support Continues Maturing

    One of the questions that came up following our GNOME 3.26 feature overview was how GTK4's Vulkan renderer is coming along.

    It's coming along as is GTK4, albeit not ready for production use quite yet.

  • You need an application icon of at least 64×64 in size

    At the moment the appstream-builder in Fedora requires a 48x48px application icon to be included in the AppStream metadata. I’m sure it’s no surprise that 48×48 padded to 64×64 and then interpolated up to 128×128 (for HiDPI screens) looks pretty bad. For Fedora 28 and higher I’m going to raise the minimum icon size to 64×64 which I hope people realize is actually a really low bar.

Canonical Needs Your Help to Figure Out a Direction for Ubuntu's Mir/Wayland

That's right, Canonical still has a team of developers working on the Mir display server, despite the Unity 8 development being dropped, and it looks like it's going into a different direction this time. The latest work by done Mir's devs involves basic Wayland support implementation, including mouse and keyboard inputs. Their Wayland Conformance Suite (wlcs) implementation also allow client to connect to the server, as well as to create windows and draw into them, but there's a lot of work to be done before they achieve full Wayland support for Mir, which involves adding essential functions like copy and paste or drag and drop.

openSUSE Tumbleweed Operating System Now Powered by Linux Kernel 4.14 LTS

Linux kernel 4.14 LTS is the latest and greatest kernel for GNU/Linux distributions, and now that it's ready for mass deployments, it will arrive in the software repositories of more distros, and Tumbleweed users are among the first to get it as OpenSuSE Project's Douglas DeMaio reports today. "The past week brought new features to openSUSE Tumbleweed with a snapshot that included Linux kernel 4.14," said DeMaio. "New features like HDMI Consumer Electronics Control support for Raspberry Pi and the merging of Heterogeneous Memory Management to the mainline this long-term support kernel are promising."
