This is necessary for some grabs, which currently have no way of knowing when the pointer/keyboard focus has left a surface. For example, without this, a drag-and-drop grab can erroneously drop into a window that the cursor is no longer over. This is the plumbing needed to properly fix swaywm/sway#5220. The existing fix, swaywm/sway#5222, relies on every grab's `enter()` hook allowing a `NULL` surface. This is not guaranteed by the API and, in fact, is not the case for the xdg-shell popup grab and results in a crash when the cursor leaves a surface and does not immediately enter another one while a popup is open (#2161). This fix also adds an assertion to wlr_seat_pointer_notify_enter() that ensures it's never called with a `NULL` surface. This will make Sway crash much more until it fixes its usage of the API, so we should land this at the same time as a fix in Sway (which I haven't posted yet). |

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.
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
- libdrm
- GBM
- libinput
- xkbcommon
- udev

Run these commands:
meson build
ninja -C build
Install like so:
sudo ninja -C build install
