On modeset wlr_output will internally allocate a buffer. The backend will emit a "mode" output event, then wlr_output will emit a "commit" event. wlr_output_damage handles the "mode" event by damaging the whole output, and then handles the "commit" event. However the commit event has a buffer, so wlr_output_damage rotates the damage in its ring buffer, thinking the compositor has rendered a frame. The compositor hasn't rendered a frame, what wlr_output_damage sees is the internal wlr_output black buffer used for the modeset. Let's fix this by damaging the whole output in the "commit" event handler if the mode has changed. Additionally, damage the whole output after rotating the damage ring buffer. |

wlroots
Pluggable, composable, unopinionated modules for building a Wayland compositor; or about 50,000 lines of code you were going to write anyway.
- wlroots provides backends that abstract the underlying display and input hardware, including KMS/DRM, libinput, Wayland, X11, and headless backends, plus any custom backends you choose to write, which can all be created or destroyed at runtime and used in concert with each other.
- wlroots provides unopinionated, mostly standalone implementations of many Wayland interfaces, both from wayland.xml and various protocol extensions. We also promote the standardization of portable extensions across many compositors.
- wlroots provides several powerful, standalone, and optional tools that implement components common to many compositors, such as the arrangement of outputs in physical space.
- wlroots provides an Xwayland abstraction that allows you to have excellent Xwayland support without worrying about writing your own X11 window manager on top of writing your compositor.
- wlroots provides a renderer abstraction that simple compositors can use to avoid writing GL code directly, but which steps out of the way when your needs demand custom rendering code.
wlroots implements a huge variety of Wayland compositor features and implements them right, so you can focus on the features that make your compositor unique. By using wlroots, you get high performance, excellent hardware compatibility, broad support for many wayland interfaces, and comfortable development tools - or any subset of these features you like, because all of them work independently of one another and freely compose with anything you want to implement yourself.
Check out our wiki to get started with wlroots. Join our IRC channel: #sway-devel on Libera Chat.
wlroots is developed under the direction of the sway project. A variety of wrapper libraries are available for using it with your favorite programming language.
Building
Install dependencies:
- meson
- wayland
- wayland-protocols
- EGL
- GLESv2
