Mouse pointer jitters or invisible GNOME 3
Using Fedora 27 and GNOME Shell 3.26.2. My mouse pointer would jitter (rapidly become visible then invisible repeatedly) or become invisible in a band approximately starting at 1/8th down from the top of the screen to about 1/3 of the way down from the top of the screen (not sure how else to describe this). After many attempts and Google searches to try to solve this issue I have had to switch to MATE desktop (which is rock solid stable). It appears to me there is some invisible overlay (in GNOME 3) that is causing this behavior.
