Slow scroll view scrolling when entering Play mode and in Builds
Scrolling is quite slow in Play mode.
We can see that the wheel delta computed by InputSystemUIInputModule is 1/10 of what we have in an EditorWindow.
Reproduction steps:
# Open the user's attached project
# Open Assets > Test scene
# Enter Play mode and scroll Expected result: usual scrolling speed Actual result: slow scrolling

The 'fix' of adjusting ScrollView's mouse wheel scroll size is only a partial solution. The slow scrolling only occurs on Windows devices, so increasing it across the board makes it go too fast on others (e.g. Mac). The slow scroll speed has been an issue since well before the concept of UI Toolkit (it was present in the original UGUI) and should be fixed on a higher level.

Would love to see this fixed in 2021.3.X if possible.
If not, is there any chance we can get a patch file or summary of changes to try to fix internally? -

Not sure if this is the sam problem the is fixed in the Alpha branch, but when scrolling in Android. It looks like the scroll after you release it, uppdates in like 10fps. While checked performance it runs 60fps, so is not a performance problem. Seems like there is a cap in the update for the Scroll Deceleration Rate tick.
Have tried to get the Alpha up and running to confirm it's fixed, but didn't manage to create a build so gave up.

I can confirm in 2022.2.0b13 the scrollview scrolls slowly, even when scroll sensitivity or vertical page size is changed.
