In time for next month's GNOME 50 release are some improvements merged today for the Mutter compositor code adding HiDPI and monitor mode emulation support to the screen-casting API and DevKit.

GNOME 50 is coming in quite heavy on the new features. The latest code to land in Mutter is a merge request that had been in the works by Jonas Ådahl the past three months for HiDPI and monitor mode emulaiton to benefit GNOME's virtual monitor and remote desktop capabilities.
