14 DAY TRIAL // The Mutter window and compositing manager is yet another important component of the popular GNOME desktop environment that received many improvements during the GNOME 3.22 development cycle, besides Polari and Nautilus.
A second Beta development snapshot of the upcoming Mutter 3.22 release, which will be available on September 21, 2016, as part of the launch of the highly anticipated GNOME 3.22 desktop environment, has been made available for public beta testing by one of its maintainers, namely Florian Müllner.
According to the internal changelog attached to the source archive, Mutter 3.22 Beta 2 is here to add several improvements to the next-generation Wayland display server, such as monitor rotation support, the ability to use the same output naming logic as X.Org Server, and better support for chat notification replies in GNOME Shell.
The xdg-foreign protocol is now officially supported
Additionally, the Mutter 3.22 Beta 2 release implements support for the xdg-foreign protocol, ports the xdg-shell implementation to the sixth generation, and adds better support for unsupported buffer sizes. Of course, there are also many minor bug fixes and cleanups, so check out the changelog below for all the technical details.
Last but not least, the Polish, German, Indonesian, Brazilian Portuguese, Serbian, and Serbian Latin language translations have been updated in this second Beta milestone of the upcoming Mutter 3.22 release, which will be ready for production on September 21, 2016, as part of the GNOME 3.22 desktop environment.
Until then, you can download its sources right now via our website and take this Beta release for a test drive. We insist on reminding you always that Beta builds are pre-release versions, which contain bugs and other issues, so don't install them on your stable Linux-based operating system.
