The mouse icon on my Mac Mini (macmini6,2 - 10.14.1) has started stuttering. It's not always, but most often. Sometimes it's so bad the icon won't move at all and I cannot click with my Magic Trackpad 2.
I've looked at Activity Monitor (and
top) but it doesn't show that it is doing much at all. I've closed down the more intensive background apps (e.g. Plex) but it doesn't seem to help.
A restart seems to improve things initially, but then it comes back.
I also occasionally see a grey box with a spinning sun like icon in it appear every so often. No idea what that is!
Looking for some guidance to locate the offending process, or if it is hardware etc.
I'm going to update macOS and see how that goes!
