    On top of the last minute GNOME 3.36 work on scaled/transformed hardware cursors handling, there is some other interesting last-minute Wayland work on the Mutter side...

    What's current status on Wayland vs X.Org, regarding performance, and power consumption, and glitches?

      Power consumption under Wayland in theory should be much lower than the previous X compositor setup. There's a reason X was avoided for phones.

      I've been using GNOME Wayland for nearly two years now and haven't noticed anything major (I've had the shell crash three times in those two years). Performance is fine unless you're running games, where there is room for improvement over input handling and Xwayland.

        What about the undirect fullscreen Wayland windows. Did that one make it?

          Nobody really cares because the xwayland bits would need to come down the line at first and there is no plan when the next X will be released.

            This release is going to be awesome it seems. Can't wait for it to land on Arch.

              Might still happen before Fedora 32 release.

                Sadly we don't. There is much more stuff in x-devel that would improve gnome / wayland. From xwayland fullscreen fixes, to tearing prevention improvements, to performance fixes, to EGL-Stream support/improvements, to async-loadup improvements, to input improvements. There is SO MUCH that would help to improve gnome experience. Yet there isnt even a target year of release.
                It might not be a blocker. Its just another feature of gnome, that is of less use, because the xorg-bits are missing.

                  No Xwayland changes required for this.

                    Don’t worry about it. Canonical got people working on GNOME and Debian.
                    Well, Ubuntu 20.04 is past Debian import freeze, which means no new packages get in. But, there might be exceptions...

                    I'm currently running Ubuntu 19.10, and then plan to upgrade to 20.04 LTS, and keep running it, until I buy a new laptop (recently I bought Lenovo A485 2700U PRO from warehouse sale, really good price).

                    There were times, when I was running Arch Linux... But, I ain't got time to maintain rolling release, anymore.
