Facing exactly same issue on fresh installation. It effects most of the default Ubuntu applications like "Ubuntu Software Center", Nautilus, Gedit etc.
Occurs when the clickpad is "touched" (not tapped) i.e. removing finger and retouching it while moving mouse pointer over the window. The work around of the "sticky scroll" is to keep sturdy touch on the clickpad without moving finger for a second and then moving. Moving finger off the clickpad and retouching it will make the issue reappear though. Firefox, Chrome and Libreoffice remain unaffected though. I am on: 15.04 64 bit Ubuntu Acer E5-571-56UR xinput for the clickpad is as under: ELAN0501:00 04F3:300B UNKNOWN id=11 [slave pointer (2)] -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1454473 Title: In Ubuntu 15.04, simply moving the mouse via touchpad scrolls the window To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1454473/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
