Mouse cursor shows a flickering matrix that starts at the mouse cursor and then flows down and to the right. Flickering matrix is about 1 inch by 1 inch and resembles a 8x8 matrix with short lines that are not connected.
- Rebooted computer
- If the mouse cursor size is incresed in the Accessibility section of the System Preferences, the flickering matrix temporary goes away.
- Same issue with Magic Mouse and Dell wired mouse
- Logged in to another admin account, no change
- Reset PRAM, no change
- If the entire screen is zoomed in at all, the flickering matrix goes away
