I reopen the bug for firefox, because other browsers don't have this
bug, so firefox causes this. If anyone knows better, please correct.
Would it make sense to open an Xorg bug for this?

Why is this bug filed against linux? Firefox uses the whole CPU.
I think the JavaScript is very bad written or firefox has a bug or (what
I assume most) there is a problem with the rendering. If the
'newsticker' moves, the whole thing must be new rendered. And if the
graphics card can't do this,
How is this invalid? It's still a major problem for me.

Also, I got a chance to test this with the mga driver, and the problem is still
there (also, the computer was a P3, and scrolling even plain text was
definitely choppy).

New information:
Using top, I noticed that most of the CPU usage during scrolling is
actually due to X, not Firefox process itself - X uses 60-90% of CPU
time, Firefox the rest. This may be normal or not, but anyway there is
another bug that has more information on that:

Most likely the free nv is faster as you can use EXA AccellMethod

Sorry, but as the nv driver man page states, EXA is only supported for

We have cairo 1.6 not 1.4. what package are you running exactly?
Now, on Hardy, I run Cairo version 1.6.0 (libcairo2 version
