white lines on icons on the dock
Since the latest update my 2020 macbook air has stripes on some of the icons on the dock, which disappear when putting the cursor on them. Why? On this screenshot it is the calendar and the google chrome icons. Some days it is other icons. The computer has also been a little skittish overall. Overheating when not many programs are open, shutting down programs in the middle of a process. Is a 2020 macbook considered old?
