Comment 20 for bug 1714459

I still see significant blurriness in Wayland compared to Xorg. I currently have gnome-shell 3.26.1-0ubuntu4, and I still see the problem. However, in comment #11, this bug report says that a fix was released for 3.26.1-0ubuntu1 on 10/6/2017.

I added the following settings in /usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.xsettings.gschema.xml and recompiled the schema so it will apply system wide.
    Hinting = 'full'
    Antialiasing = 'rgba'
Dconf confirms that the system using these default values, as configured above.

When I log into a Wayland session, the desktop fonts respect these settings, but gnome-shell fonts look terrible. The fonts from the topbar, all dropdowns from the top bar, and right-click pop-ups from the dock are extreemly fuzzy.

When I log into an Xorg session, gnome-shell fonts look great, very sharp, and clear. There is a significant difference between gnome-shell on Xorg and Wayland.

I've attached the following screen-shots to help illustrate the difference:
- Wayland on Ubuntu 17.10.png - Screenshot of Wayland + gnome-shell topbar, gnome-shell notifications, and Nautilus on Ubuntu 17.10
- Xorg on Ubuntu 17.10.png - Screenshot of Xorg + gnome-shell topbar, gnome-shell notifications, and Nautilus on Ubuntu 17.10
- Wayland vs Xorg on Ubuntu 17.10.png - Screenshot, zoomed in 1500%, showing font rendering differences between Wayland and Xorg

Depending on your monitor and resolution, you may not see the difference between the two attached pictutes "Wayland on Ubuntu 17.10.png" and "Xorg on Ubuntu 17.10.png".

Nevertheless the third image, " Wayland vs Xorg on Ubuntu 17.10.png", should help. In this image, you can actually see the sub-pixel font rendering, and you can see that grayscale is being used in Wayland (even though I have configured 'rgba'). I will aslo assume that my system setting of 'full' hinting is being ignored as well, by Wayland.
