Comment 4 for bug 1691676

Adding this story so maybe it will be easier for others to find.

When I upgraded to Ubuntu Artful Aardvark 17.10 the screen booted up in zoom mode and it scrolled whenever I moved the mouse. I figured out how to get the zoom to normal size, but the mouse cursor disappeared or was invisible. If I pressed any key (e.g. SHIFT), the cursor would flash and I could repeatedly press the key to navigate.
I didn't realize the Universal Access Zoom was still on because the zoom was 1:1. Turning the zoom feature off entirely made the mouse appear as normal.

Perhaps the Universal Access Zoom should be off by default on updates.
