Article Summaries:

  • Summary

On February 19, Collabora released Weston 15.0, the reference Wayland compositor. The update introduces a Lua‑programmable shell, enabling developers to script compositor behavior directly. An experimental Vulkan renderer is added, alongside smoother media playback and expanded color‑management features. Weston’s core focus on efficient use of display hardware is reinforced, with recent work reducing CPU usage even on low‑end devices. The release also brings built‑in support for the Perfetto profiler, improving diagnostics and performance tuning. These enhancements aim to make Weston more flexible, performant, and easier to profile for developers.

  • Summary

On February 19, Collabora released Weston 15.0, the reference Wayland compositor. The update introduces a Lua‑based shell, enabling developers to script compositor behavior, and an experimental Vulkan renderer for improved graphics performance. Additional enhancements include smoother media playback, expanded color‑management features, and a refined display stack that offloads more work to fixed‑function hardware while reducing CPU usage. To aid debugging and performance tuning, Weston 15 now supports the Perfetto profiler. These changes aim to deliver a more efficient, flexible, and developer‑friendly compositor across a wide range of devices.

  • Weston 15.0 Released with Lua Shells, Vulkan Rendering, and Performance Enhancements

Collabora’s Marius Vlad announced Weston 15.0, the reference Wayland compositor, on February 19. The update introduces a Lua‑programmable shell, an experimental Vulkan renderer, and smoother media playback. It also adds new color‑management features and expands support for the Perfetto profiler. The release focuses on improving efficiency on low‑end devices by better leveraging GPU and display hardware while reducing CPU usage. Overall, Weston 15.0 aims to provide a more flexible, high‑performance display stack for Wayland‑based systems.

  • Vlad: Weston 15.0 is here: Lua shells, Vulkan rendering, and a smoother display stack Over on the Collabora blog, Marius Vlad has an overview of Weston 15.0, which was released on February 19. Weston is the reference implementation of a Wayland compositor. The new release comes with a new shell that can be programmed using the Lua language, a new, experimental Vulkan renderer, smoother media playback, color-management additions, and more. One of Weston’s fundamental pillars has always been making the most efficient use of display hardware. Over time, all the work we did to track and offload as
