161630 - Scrolling window causes visual artifacts

Status: RESOLVED DUPLICATE of bug 51385

(Core Graveyard :: GFX, defect)

Description

[Scott Gifford]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1b) Gecko/20020807
BuildID:    2002080708

When I view certain pages in windows which are in certain positions and of
certain sizes, I see artifacts when scrolling vertically with the thumb.  I have
to move the thumb at a particular speed to get this to happen, but it seems to
happen fairly often in normal use.


Reproducible: Always
Steps to Reproduce:
1. Start up a mozilla window 876x790 pixels at an offset of 62+55 viewing the URL:

    http://bugzilla.mozilla.org/show_bug.cgi?id=157592

I do this by running:

    mozilla -P default -geometry 876x790+62+55 \
      'http://bugzilla.mozilla.org/show_bug.cgi?id=157592'

from the shell.

2.Scroll the page up and down with the thumb in the vertical scrollbar.  Try
dragging the thumb at different speeds (I usually have to try a couple times,
but I can reproduce it consistently within 30 seconds or so.


Actual Results:  Ugly grey visual artifacts.


Expected Results:  No artifacts.

The artifacts seem to come from the grey area next to the horizontal scrollbar,
but that's more of a feeling than anything.

resolving as dup of bug 51385.
It seems to be remnants of the CC list that duplicates down the page.
