I guess you did have Hardware Acceleration turned on here. What can be the problem then? I am consistently experiencing this issue with my Radeon HD4890 and the catalyst 10.3 drivers. Could it be the drivers?
I'm not 3d guru so writing here about ATI would be only a speculation.
And yes, as in bug 22730 everything checked in Graphics Options, including Hardware Acceleration. I have exactly the same scrolling speed in left & right direction and also same in up & down direction.
