479722 - SVG filter dirty rect does not account for shape movement

Status: RESOLVED DUPLICATE of bug 463939

(Core :: SVG, defect)

Description

[Martin]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2a1pre) Gecko/20090221 Minefield/3.2a1pre
Build Identifier: 

When a shape with a filter applied is moved, only the *new* filter output region is repainted immediately, the old filter output region is left unchanged until invalidated by other means.

This is a regression from Firefox 3, presumably the filter region optimisations.

Reproducible: Always




This is one of a number of filter dirty rect problems I've run across on trunk, but the first I can't work around.

Attachment: Testcase

This is as far as I could reduce it, requires scripting and change has to happen after first render.

Screen should flash red then turn lime, with trunk it remains green until you tab out and tab back or drag another window in front or whatever.
