There is no touchscreen. I have Lenovo Z510 laptop with tachpad, but I mostly use mouse with wheel. I usually use mouse wheel to scroll web pages, and now with "smooth scrolling" enabled in dconf I have very slow kinetic scrolling , no matter if I use touchpad, or mouse wheel... scrolling takes "ages" now.

I had tried few releases... same problem with 2.11.90, 2.11.5.
With 2.11.4 everything is OK again. With "smooth scrollong" enabled, scrolling useing mouse wheel and touchpad is smooth but not kinetic, and with normal speed.
So it seems that 2.11.5 release introduced the regression.

My english is not very good, sorry.
