Describe the bug A clear and concise description of what the bug is.

When moving my finger back and forth very fast on the touchpad, as if to spam movement, the cursor instead freezes.

I need this behavior (moving very fast on touchpad to spam moving cursor very fast) to play rhythm games on the touchpad.

This works correctly on my builtin touchpad on Windows, and it works correctly when connecting the Apple Magic Touchpad 2 to the same computer when running Linux, with native Linux drivers. I'm just now trying to do the same on Windows, via mac-precision-touchpad, and it isn't working.

To Reproduce Steps to reproduce the behavior:

1. Move a single finger fast back and forth on the touchpad
2. Keep moving back and forth faster and faster, as fast as possible

Expected behavior A clear and concise description of what you expected to happen.

I expect the cursor to continue moving back and forth at faster and faster speeds. It should never stay in the same place, and instead continue moving significant amounts back and forth on the screen.

Instead, after some speed threshold is reached, it freezes in a single location. Notably, after it freezes, moving slowly does not fix the problem. Instead, the cursor stays in that location until I lift up my finger at least once.

Traces If applicable, add WPP traces to help explain your problem.

Environment Add your device model, driver type (USB or SPI) and OS version here.

I'm using an Apple Magic Touchpad 2 via a USB connection. Running Windows 10 version 20H2 on a Thinkpad X1 carbon 2015.

I installed mac-precision-touchpad via chocolatey.

I think this may have to do more with the position/angle of your finger than the speed. I can move my mouse cursor very fast without it stopping if I don't move my finger down and out (which is the natural thing that happens when I try to move my mouse cursor very fast because it's easier to do than with the tip of my finger -- hard to describe with words vs video but hopefully it's clear enough). I posted an issue about how this type of position (where more of the "ball/pad" of your finger is on the trackpad) causes the mouse cursor to stop moving (sometimes/intermittently). I experience it a lot in spreadsheets where I'm just trying to move my mouse cursor down/down and over just one or two cells. I do this a lot on my macbook with no problem but on my PC with the trackpad I very frequently have a problem where the mouse stops moving.

Hopefully this can be fixed with the sensitivity/filtering fix that'll (hopefully) be released soon.
