Comment 14 for bug 403869

I think I didn't provide enough information with my first comment. So the problem is that I cannot reproduce the effect on my touchpad, scrolling works all the way up to the right edge.

These things are simple to reproduce with software test devices as you can force a device to look a certain way and you can force a distinct set of events.

With the patch above, the cursor simply moves left/up to right/bottom and back. This wouldn't trigger scrolling on any touchpad, so the test device as is cannot be used to reproduce the bug.

Please modify the test device's run method to send events that trigger scrolling in the first region but don't trigger scrolling in the second region (even though they should). I can then run this here and see what happens in the driver.
