Tested on Windows, might happen on other platforms, not sure
tested with Dell 2in1 laptop w/ precision touchpad and touchscreen
Description
To reproduce, try creating a flickable containing a large scene, for example 8000 small rectangles. (you don't need this many to see a noticeable difference, however), and try scrolling using a touchpad
As you can see in the video, in the exact same scene, scrolling with my laptop's touchscreen works perfectly smoothly, but scrolling with a touchpad causes huge amounts of lag and erratic/jerky scrolling
When I sent a demo of my app to a friend (without the dots at the end, i added that in to make the bug more visible for the video), they were very annoyed by this bug too, they noticed that scrolling with their touchpad was very laggy, but with their touchscreen it was perfectly fine.
