Leaves a trail of stuff below that should not be visible.  See picture
attachment, try steps below.

Reproducible: Always

Steps to Reproduce:
1.  Open file new bug page at URL above (just as a test, don't file.. :)
2.  Go to "Component" section drop down menu.
3.  Scroll to bottom of list.
4.  Select the last entry. (in this case, "URL Bar & Autocomplete")
5.  Now click the up-arrow a bunch of times or slowly scroll list up.
Actual Results:  
Weird dashed line artifacts show up below window proportional in speed to
scrolling... Only happens scrolling the list in the up arrow direction from the
bottom--the exact opposite direction behaves properly at the top.


Expected Results:  
Nothing should ever show up outside of the window.

Seen this during bug reports from an iMac G3 and an iBook (both have ATI grfx).. 
Anyone test this out on a GForce display?  Looks like a layering issue... not
sure.  Low bandwidth connection here, can't test nightly builds, link seems
usually down anyways.
