Scroller unexpected behaviour with free-spin mouse.
Open, NormalPublic


I have mouse with MicroGear wheel.

Steps to reproduce:

  1. Enable free-spin scrolling on mouse
  2. Start "elementary_test -to "Scroller 2"
  3. Start to fast spin wheel to scroll in direction from beginning to end.

Scroll button goes to beginning of scrollbar and stay there until wheel stops turning.
Scroll button goes to end of scrollbar.

Umm... Is there any way to test without special hardware?

Btw this test case reveals an incredible performance issue with this scroller, clip recalc, etc... I had tried to look at it before, but with not much luck. So it could be that the calculation logic is really off and causes both the performance to be abysmal, as well as the behaviour you observe.
