Zoom making voiceover sluggish and freezing on an iPhone 14 pro max

Hi all,

My wife is using an iPhone 14 pro max. She uses magnification and sometimes voiceover.

She is using the zoom feature which magnifies the entire screen. This is enabled by activating it in the vision settings.

She is on IOS version 16.6 and no newer updates are available.

She is also using settings to enlarge the fonts on the phone.

I tried navigating her phone with voiceover and find that swiping and all other gestures are really sluggish. I can't even do the Roter gesture.

Is anyone else experiencing this? Are there any workarounds?
