Right page is shifting when turning pages forward

[rver]

When you turn pages forward, the right page is shifting (about 1 pix) at the end (when the left page finishes its move).
The problem doesn't exists when turning pages backwards.

(the shift puts the right page in its correct position. The problem is the position of the right page during all the left page movement.)

Sadly, I can still reproduce this... with Chrome. With Firefox, everything seems OK. Not sure what's going on yet. Doesn't seem to be affected by 4e10a4d.
