the performance on XF is much better than MAUI

Steps to Reproduce

The performance between XF and MAUI is close here. The main lag seems to be from updating the layouts/bindings.

If you scroll really fast hon MAUI the fields just take a moment to update.
XF also isn't perfect here, it flashes weirdly and the layout is incorrect.

MAUI:
MauiCV.zip

XF:
XFCVUWP.zip
