Smooth scroll experience in PDF

[ZZYSonny]

Thanks to the edge team's work, Surface's precision touchpad experience on websites are pretty nice. (With #edge-experimental-scrolling it even has some bounce effect)

But using touchpad to zoom in, zoom out, scroll on PDF lags a lot. The fps seems to drop to ~10， making a bad reading experience. However, there is no fps issue using touch screen to do the same action.

I know PDF features are still getting worked on, but is this happening on Dev or Canary? (or both)

The touch screen has no issues still?

Thanks,

I am using Dev version 77.0.230.2. Touch screen seems to be better than touch pad in most time but still not as smooth as browsing web page.
