Would be useful to have a writeup of what you think happens there, > mainly for comparision/inspriration. On macOS, if I move the mouse cursor with one finger, and then drop a second finger while the cursor is on a window that can scroll, I observe the following (test done by moving the cursor from top to bottom): # If my mouse cursor is travelling at about 100px/s or more, the second finger has no visible effect. The cursor keeps moving. # If my mouse cursor is moving at 20px/s or less, then the second finger immediately activates scrolling much like in Linux. It's hard to measure the threshold precisely. I don't know of a tool for that. I'll do a test under Windows if I can revive my last PC laptop.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
