Mutter 3.22 Release Candidate is now ready for testing

Sep 14, 2016 22:20 GMT  ·  By

The GNOME 3.22 desktop environment should soon get a Release Candidate (RC) version, which marks the end of its development cycle before the final launch on September 21, 2016.

GNOME 3.22 Release Candidate should be out later today, September 14, 2016, but until it arrives, we would like to tell you a little bit about one of its core components, the Mutter window and compositing manager, which has been updated recently with several fixes for the Wayland display server.

Mutter 3.21.92 (means 3.22 Release Candidate) is out now, and looking at the release notes, we can notice that animated cursors now work again on Wayland, along with absolute pointer motion events and XWayland pointer warp emulation. Moreover, several nasty crashes have been patched for Wayland as well.

The Fedora 25 Linux operating system, due for release in mid-November this year, promises to offer Wayland as the default display server for the Workstation edition, which will use the upcoming GNOME 3.22 desktop environment, so these fixes are necessary to ensure an out-of-the-box experience for users.

Common monitor modes were added in the KMS backend

Among some other improvements that landed in the Mutter 3.22 Release Candidate build, we can mention the implementation of common monitor modes to the Kernel Mode Setting (KMS) backend, the ability to compress motion events instead of discarding them, and support for using g-s-d schemas for tablet configuration. Several language translations were updated as well.

Last but not least, Mutter now defaults to use stage views, which received some improvements for the built-in screen capture functionality. Mutter 3.22 RC is now available for download, as a source archive, via our website, but please try to keep in mind that it is a pre-release version, not to be installed in production systems. Below, we've attached the full changelog for more details.
