GNOME Shell and Mutter Fix Touch Interaction and Pointer Emulation on Wayland

There are more and more updated GNOME apps and core components released on the project’s FTP servers as part of the forthcoming GNOME 3.19.3 desktop environment, which should be available later today.

Therefore, we can report that the GNOME Shell user interface and the Mutter window manager have been updated to version 3.19.3, the third development milestone towards the major 3.20 release.

Looking at their changelogs, we can notice that Mutter now presents the right refresh rate units on Wayland/KMS, forces two-finger scroll by default, and addresses a crash that occurred when XWayland was initialized.

It patches two other crashes, one that occurred when the initial position of the mouse cursor was not on a monitor and the other when enabling more CRTs than connected outputs.

The touch pointer emulation now works correctly on the Wayland display server, it is now possible to minimize windows that do not support Mutter, and a ConfigureNotify alert is now sent only to mapped windows.

On the other hand, GNOME Shell 3.19.3 adds a fix for scaling of thumbnails in the window switcher when using the desktop environment on HiDPI displays, and makes sure that animated backgrounds are now being updated during timezone changes.

Additionally, it fixes touch interaction when running on top of the next-generation Wayland display server, and makes sure that the user list is updated when changes occurred to users.
