Resolved: MacBook Air M4 partial double screen

this isn't really question but an answer to my previous question:

Sudden partial double screen displays on MacBook Air M4 silicon...

I posted this in July after I got my newest MBA. However the responses didn't resolve my issue. Recently I found the answer 'by accident!': I double tapped the trackpad with 3 fingers .... viola! The partial double screen disappeared!!

MacBook Air 13″, macOS 26.1

The “partial double screen” wasn’t a display issue — it was a Look Up preview window activated by a 3-finger tap/double-tap.

Tapping again dismissed it because you toggled the gesture off.
