Testing with the latest (Nov. 16) birch nightly.
Long pages are sometimes cut off at the bottom, some are cut off at the right side as well.
For example, open https://wiki.mozilla.org/EU_MozCamp_2011/Schedule.
Most of the time, I don't see the bottom of that page. If I zoom in and press Reload, it gets better.
Zooming in too much is counter-productive however. If I do this on http://www.heise.de/newsticker/ and pan upwards, I scroll both the page (new text is pulled out of the checkerboard), but also move the visible content upwards and see more of the checkerboard (but not the bottom of the page) until the page is gone.
Another nice example is about:about. Zoom out and press reload, zoom out further and press reload etc., until only the heading (or the first letter of it) is visible (zoom in to check). This is reversible by zooming in and reloading. It also affects the next page you're loading in the same tab.
Maybe bug 701594 (Should not be able to stay zoomed out further than the page width) will help here.
I am able to load https://wiki.mozilla.org/EU_MozCamp_2011/Schedule on today's native build would you please recheck.
It got better, i.e. it displayed the whole page. But if you zoom out on that page or on about:about, it is cut off.
It will be fixed by the "css-zoom" patch on

This just got fixed by the pan-zoom-patches (bug 703141).

Pages are not cut off: verified on long pages (https://wiki.mozilla.org/EU_MozCamp_2011/Schedule) and also with zooming out and reloading.
