Bug Description

Summary:

Scrolling in Ubuntu Software Centre using the touchpad is broken - scrolling down (for example) causes the screen to judder and make no downward progress.

Steps to reproduce:

1) Enable two-finger scrolling (n.b. touchpad configuration is currently handled by "Pointing devices" - replacement for gsynaptics in the Software Centre).

2) Open Ubuntu Software Centre.

3) Attempt to two-finger scroll down the page - the screen simply judders (almost as if two source of scroll events are fighting to scroll in either direction).

Note that, strangely, touchpad scrolling works fine when the cursor is on the right of the screen (approximately the right quarter of the screen).
