281938 - dragging a window across an image scars that image with by stripes

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Wenqing Jiang]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b) Gecko/20050210 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b) Gecko/20050210 Firefox/1.0+

Please look at the attached screen shot (will attach it immediately after
this bug report).  The browser window displays Yahoo home page.  I dragged
a small notepad window over one of the home page's images, and that image
was left with white stripes, showing the contour of the movement of the
left boarder of the notepad window.  - this is problem #1.

The image will restore to normal if I simply click on the browser window
title bar to make it the current window.  That seems to imply that the
browser would redraw the image when it becomes current window.  If that's
true, it's problem #2, because the redraw should be unnecessary if problem
#1 is solved.

Firefox v1.0 does not have problem #1.  (So I'm not certain if it also
redraws.)

Reproducible: Always

Steps to Reproduce:
1.go to Yahoo.com
2.open a small window and drag it slowly across some of the Yahoo page images
3.some images will be left with stripes (white or other color), and this can
  always be repeated.  For other images which won't be scarred, they will never
  be scarred no matter how many times you try it.

A bit of new finding: the problem occurred when the display color depth
is 32 bits.  For 16-bits color depth, there's no problem.  I'm using
Windows XP, with display DPI setting as "Large size 120DPI, 125% normal
size" in both cases.

Sorry, I found the problem still occurs after I changed the display color
depth back to 16-bit.  The ff I use is 20050328.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that

highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
