           Summary: interactive map slow because of full screen redraw
                    when display:inline
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
               URL: http://vis.uell.net/testcases/atlas_inline.xhtml
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: svg at live.de

The following was reduced during SVGopen 2010 in Paris:

Given this interactive map (439 paths), hover over the map and the underlying polygon changes its color. 

In this standalone SVG only the affected polygon gets redrawn (checked with Quartz Debug)
http://vis.uell.net/testcases/atlas.svg

Now we put the SVG map in some XHTML document and change some text in the HTML part when hovering over the map

Scenario A (=default), the SVG has a "display:inline" style
http://vis.uell.net/testcases/atlas_inline.xhtml
Hovering over the map leads to a full screen redraw even of areas not affected

Scenario B, the SVG has a "display:block" style
http://vis.uell.net/testcases/atlas_block.xhtml
Hovering over the map only redraws the affected areas
