** Description changed:
+ [ Impact ]
+
+ Using the screen magnifier ("desktop zoom") feature results in some
+ visible screen corruption if you use multiple monitors side-by-side.
+
+ [ Test Plan ]
+
+ 1. Configure your desktop with at least two monitors, side-by-side not
mirrored.
+ 2. Press Super+Alt+8 to enable the magnifier.
+ 3. Move the mouse around and verify that all parts of both monitors are being
+ updated without any signs of corruption, particularly at the edges.
+ 4. Press Super+Alt+8 to disable the magnifier.
+ 5. Open Settings > Accessibility > Zoom and change the Screen Area setting to
+ verify steps 2-4 again in each mode.
+
+ [ Where problems could occur ]
+
+ The fix only modifies the magnifier feature, but that feature has
+ multiple modes so be sure to test all Screen Area options as mentioned
+ in the test plan.
+
+ In the absolute worst case, modifying gnome-shell's JavaScript can
+ result in unpredictable runtime failures for code paths that are not
+ tested because it is compiled just-in-time.
+
+ [ Original description ]
+
Pressing Super+alt+8 to zoom with multiple displays results in a screen-
sized area zooming in the middle of my extended display; i.e. split
across the two physical displays. When I move the mouse the zoomed area
follows the mouse, and the area outside of the zoomed area stops
updating, it just displays the way it looked when the zoom was last
there. See attached image.
