2. Open the “SampleScene“
3. Enter Play Mode
4. Press any part of the Game view with a pen and slowly drag downward
5. Observe the Game view and the Console

Expected result: Cube moves smoothly in the Game view, Console outputs steady negative Y delta
Actual result: Cube moves in a stuttery manner, Console outputs continuously changing positive and negative Y delta

Reproducible in: 1.8.2, 1.14.0 (2022.3.62f1, 6000.0.49f1, 6000.1.3f1, 6000.2.0a1)

Tested with devices: Wacom Intuos (CTL-4100WL) (locally), Wacom Intuos 4 (by the reporter)
