Horizontal lines - bottom of screen
I have a Macbook Pro 2017 - 13 inch with horizontal lines appearing all over the dock as shown in the pic. They start to appear after roughly 2 hours of use and they disappear if I shut the laptop down, let it cool off (then they reappear again after some time).
Anyone with similar problem? Any help ?
Thanks
MacBook Pro 13″, macOS 12.3
