Labwc 0.20 lands with show-desktop, HDR10 and window capture

Published on May 27, 2026 | Translated from Spanish

Labwc, the stacking Wayland compositor that directly draws from the aesthetics and philosophy of Openbox, has released version 0.20. This lightweight project based on wlroots incorporates features that users of minimalist desktops have been requesting for a long time. Among the main additions are the show-desktop function, window capture, and support for HDR10 when using the Vulkan renderer. All of this is now available in its GitHub repository.

HDR10 Support and New Configuration Options 🖥️

The implementation of HDR10 in Labwc 0.20 comes hand in hand with the Vulkan renderer, an option that until now was not a priority in such lightweight compositors. Additionally, the ability to capture individual windows has been added, useful for those working with multiple monitors or needing to record specific applications. In the configuration section, new options have been included to customize mouse behavior and workspace management. All of this while maintaining a resource consumption that doesn't spike the laptop's sensors.

Show-desktop: Finally We Can See the Wallpaper Without Paying a Toll 🐱

The show-desktop function arrives in Labwc as if it were the messiah of tidy desktops. Until now, if you wanted to see your wallpaper, you had to minimize windows one by one, like a digital peasant from the last century. Now, with a single shortcut, everything disappears. That said, don't expect spectacular animations or blockbuster-worthy transitions. This is minimalist Wayland: windows vanish without frills, but at least you can show off your wallpaper of a cat wearing a hat.
