487798 - Div with overflow=auto containing a table with more than 3000 rows garbles content

Status: RESOLVED DUPLICATE of bug 215055

(Firefox :: General, defect)

Description

[umautone]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.8) Gecko/2009032609 Firefox/3.0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.8) Gecko/2009032609 Firefox/3.0.8

Create a scrollable div that contains a table with more than 3000 rows. 

If you jump to the bottom of the content the whole div becomes black. 

If you scroll down normally through the rows using the arrow key or dragging the scroll bar with the mouse, you'll see the last "good" row (somewhere about 1/2 to 3/4 of the way through the content, depending on the size) stops rendering correctly and seems to smear the content.

This only happens on the Windows versions of Firefox and occurs in all versions including the latest 3.1.

This does not happen on the Mac version. Content renders correctly.

Reproducible: Always

Steps to Reproduce:
1. create scrollable div with overflow=auto perhaps 1/2 screen size
2. create large table within the div of about 3500 rows or more
3. scroll through the content or jump to the end


Expected Results:  
Scrolling smears the content at some point or turns black if jumped to the end.
