The screens colors will wildly distort for 2 seconds with a psychedelic saturated look; and the mouse cursor will turn black.
Screen Color Distortion in 12.1 Beta 3 when using Aerial Screensaver
My Mac Literally started tripping yesterday right after the update , Apple told me I should uninstall , but then what? lol
The problem seemed to occur because of the Aerial screensaver; do you use that too or was it another app? It usually resolves with a mouse shake.
