GNOME Mutter 3.21.4 Released WIth New Screen Capture API, NVIDIA vRAM Robustness

Various GNOME software components were checked in today in preparation for this week's GNOME 3.21.4 development release.

When it comes to the Mutter 3.21.4 compositor / window manager release, there are a few new features on top of fixes. This 3.21.4 release includes the frame-buffer / display work I talked about this morning that should allow multiple monitor setups to have different DPIs, among other design improvements. There is also improved X11 to/from Wayland copy/paste interaction, support for the NV_robustness_video_memory_purge extension, a screen capture API has been added to Mutter itself, and various other fixes/improvements.

NV_robustness_video_memory_purge on supported OpenGL drivers allows for Mutter to be notified when video memory has been purged/lost so Mutter can re-generate the contents as needed.

Mutter 3.21.4 details here.

Also out today is GNOME Shell 3.21.4 and it comes with various fixes and improvements.

These changes plus many others are building up for the GNOME 3.22 release come September.
