Bug Description
When using the GNOME magnifier (Zoom) feature the magnified display flickers when used in any of the following none full screen modes: Left, Right, Top or Bottom screen part. This occurs when the mouse moves towards the edge directly opposite to the magnified view. This also occurs if 'Magnifier extends outside of screen' is enabled.
To reproduce:
* Open GNOME Control Centre.
* Go to Universal Access.
* Click on Zoom.
* Enable Zoom
* Selct either Top, Bottom, Left or Right from the screen part drop down list.
* Move the mouse cursor to the opossite edge of the screen to that where the magnified view is located.
I have tested on multiple systems running Ubuntu 18.04, 18.10, 19.04 and Fedora 30.
Tested with all extension uninstalled.
Happy to provide additional details.
