Bug 12436 – repaint issue when scrolling in html file with svg embedded: raster image embedded in SVG doesn't always correctly repaint

• Status: RESOLVED
• Resolution: FIXED
• Component: SVG

This bug is perhaps not reproducable every time. I would appreciate if someone else would have a look at this well.

When I scroll in the given HTML (where an SVG map is embedded, which has a png image embedded) and I scroll as far as down that the SVG file is still partly visible and then I scroll up again, parts of the relief aren't repainted. See screenshot here: http://www.carto.net/neumann/webkitsvgbugs/screenshot_repaint_problem_when_scrolling.png

It seems like the vector part of the map is correctly repainted, but the raster part isn't.

Thank you for having a look at the issue!

this seems to be an <image> invalidation issue.  I thought we had fixed all those, but I guess not.  Probably confusion due to RenderSVGImage inheriting from RenderImage.

I can't reproduce it using ToT. Hopefully it is fixed by now?
Cheers,

yes, it seems to work fine in the current trunk - you can close this bug

I checked with both Intel and PowerPC versions

Thanks,
Andreas
