Comment 0 for bug 1831144

If you attempt to change the mouse cursor tracking mode in the gnome control centre UI for the gnome magnifier the radio buttons have no effect. If yous use dconf-editor to manual change the option at: org.gnome.desktop.a11y.magnifier.mouse-tracking the setting will have an effect.

To reproduce
* Open gnome control centre and select universal access.
* Click on Zoom.
* Toggle between "Keep the mouse cursor centred" and the other two options (proportional and push).
* If you enable Zoom and change these settings they have no effect.
* Open dconf-editor.
* Navigate to:

    org/gnome/desktop/a11y/magnifier/

* Select the mouse tracking entry and change the setting to different values while the Zoom is enabled. The setting will change the way the mouse tracking behaves.
