Status: RESOLVED WORKSFORME

(Core Graveyard :: GFX, defect)

Description

[Neil Green]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Macintosh; U; PPC; en-US; rv:0.9.9+) Gecko/20020418
BuildID:    2002041803

When scrolling through a web page with a dialog or alert box (such as the 'Find
in This Page...' dialog) on screen, graphic 'artefacts' of the box are scrolled
up and down with the page.

Reproducible: Always
Steps to Reproduce:
1.Visit a web site with a page long enough that it requires scrolling.
2.Open the 'Find in This Page...' dialog and position it in the centre of the
browser window.
3.Using the scroll thumb on the browser window, scroll the page up and down and
observe the dialog.

Actual Results:  Graphical artefacts from the dialog are 'smeared' up and down
the browser window.

Expected Results:  Mozilla should either not allow scrolling when an alert or
dialog is on screen, or it should allow the page to be scrolled 'cleanly'.

It works fine here with Mac OS 9.2.2 and Mozilla/5.0 (Macintosh; U; PPC; en-US;
rv:1.0rc1) Gecko/20020417 with Build ID: 2002041711. I tried to reproduce it on
this very page. No problem at all.
