This has been a software bug since I think one of the updates half way through the Ventura cycle. For me it happens on every MacBook Air I have (three of them) plus my external Magic Trackpad. When I go to the Apple Store, it happens on every MacBook Air on display. It does NOT happen on the MacBook Pros on display at the store. But it does if I switch their display refresh to 60 Hz (which is the norm on MBA's, while on MBP's the "pro res" refresh is default). So it is tied to screen refresh rate. The one time I had the opportunity to downgrade a MBA to a version of macOS before that Ventura update, the bug went away, as expected. The bug makes pinch+zoom basically unusable. Ctrl+scroll is not a replacement--that zooms the entire screen, not just the content. I have left feedback for Apple countless times and no progress in the two years since the bug appeared. It's incredible because Mac's entire business model is based around one thing: natural usability. This bug is the worst ball drop I have ever seen from Apple, period. As soon as I have time I plan to downgrade to the version before that Ventura version, and I will NEVER update until the bug gets fixed.
