Mouse cursor disappears on Mac client every minute

My mouse cursor will disappear in Starcraft 2 when playing ranked 1v1 and 2v2 matches and custom 1v1. It happens every minute and the last known good patch was 1 month ago. I have to Cmd-tab to get the mouse back. The mouse only disappears when in a match and not in the game lobby and not in macOS when Starcraft is closed. I know it’s a “mouse disappears” issue because I can open Starcraft menus and see the buttons highlight as if they have a cursor over them, but there’s no cursor.

I restored to the default mouse settings in Starcraft. I tried turning off “Mouse Sensitivity” too. Did not fix the issue.

macOS 10.14.6
Battle.net 1.23.2.12210
Starcraft 5.0.1.81009
1 monitor
Mouse: Microsoft Basic Optical Mouse 1113
