239704 - Moving focus rectangle using "Tab" key redraws whole page

Status: RESOLVED EXPIRED

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Leonid Romanov]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8
Build Identifier: 

When moving focus rectange via "Tab" key between links on attached test page,
Mozilla redraws whole page (all tiles and image of Tux), whereas it should
redraw only couple of tiles. 

Reproducible: Always
Steps to Reproduce:
1. Download attached test page tarball
2. Uncomment TRACE_IMAGE_ALLOCATION and DEBUG_TILING defines in
gtk/src/nsImageGTK.cpp
3. Compile TestGtkEmbed for GTK2 toolkit
4. Open test page in TestGtkEmbed 
5. Press "tab" key several times to move focus between links
6. Look at debug output from nsImageGTK.cpp

Actual Results:  
Everytime "tab" key is pressed, Mozilla redraws whole page, i.e. it redraws all
the tiles and Tux. 

Expected Results:  
Mozilla should redraw only the area damaged by movement of focus rectangle, i.e.
couple of tiles.

It is regression. Mozilla from 09-Mar-2004 doesn't have this bug, but Mozilla
from  10-Mar-2004 does.

Changed "Component" from "Layout" to "Event Handling". Sorry, didn't notice
"Event Handling" while filling the bug.
