Please see report ID # 28091179. This feels really wrong. The relay of up/down scrolling actions on the trackpad to Windows is completely broken. I have to move fingers by close to one full inch to get Windows to trigger a response. Next to impossible to work comfortably in Visual Studio for instance. It has been ongoing for the last 4 hours (since I upgraded) and I am becoming mad at it! Where is my backup so I revert to the last beta build ?... Had no such issue there.
