The GNOME 49 Mutter beta release is now available for testing ahead of the stable release of GNOME 49 coming up In September.

The Mutter 49.beta compositor has re-introduced snippet caching support, fixes drag-n-drop for X11 clients using a tablet stylus, respects implicit grabs for pop-up surfaces, fixes a possible crash, and has several Wayland fixes.

Wayland changes in Mutter 49 beta include implementing the wl_fixes interface, creating a MetaWaylandClient for every Wayland client (wl_client), and implementing support for the pointer warp protocol.

[1]Wayland Protocols 1.45 from June introduced the pointer warp protocol. This pointer warp support to complement pointer locking and more will be useful for some Wayland-native games moving forward as well as some applications for infinite panning type situations.

Mutter is only allowing pointer warping while an implicit grab is held. More details via [2]this MR .

Support for wl_fixes in Mutter had been open [3]since last July and only merged now for the upcoming GNOME 49 release.

More details on today's GNOME Mutter 49 beta release via [4]GNOME.org GitLab .
