GNOME --
Mutter 3.27.1 has just been released as the first development release for the GNOME 3.28 cycle of this compositor / window manager.

The change most interesting to us about Mutter 3.27.1 is support for hybrid GPU systems. The context for the hybrid GPU system support is explained via this bug report, "supporting systems with multiple GPUs connected to their own connectors. A common configuration is laptops with an integrated Intel GPU connected to the panel, and a dedicated Nvidia/AMD GPU connected to the HDMI ports."

Mutter should now play happier in these environments thanks to low-level code changes by Jonas Ã…dahl for dealing with hardware cursors across multiple GPUs, removing legacy rendering code, supporting hybrid iGPU/dGPU blitting, and other code improvements.

Mutter 3.27.1 also now has support for dealing with clients requiring an older version of the DMA-BUF protocol, prevent crashing when closing maximized windows, some HiDPI tweaks, and various fixes.

More details via the gnome-announce-list. GNOME 3.27.x development releases will continue until the GNOME 3.28.0 stable release next March.
