Scrolling problems get worse with complicated sources. Try
color-theme-library.el.  It is already happening with the default font
(Courier New). But selecting fixedsys font for example is making it
far worse. It happens when scrolling down with C-n. I hope tis can be
fixed because it keeps me from using 23 and I stick with 22 as the
problem does not exist there. It may have something to do with the new
font engine, I don't really know though...
