1. Set svg.style.backgroundColor = "blue" 2. Notice the svg element does not change 3. Resize the window and notice the background updates Testcase below: <!DOCTYPE HTML> <html> <head> <script> function test() { var svg = document.getElementById('svg'); setTimeout(function() { svg.style.backgroundColor = "green"; }, 100); } </script> </head> <body onload="test()"> This test passes if there is a green rectangle below:<br/> <svg id="svg" width="100px" height="100px"> </svg> </body> </html> This has been fixed in Blink. We just need to merge the patch from crbug.com/354305.

The newly failing tests are all using an `overflow: visible` style, so this is most likely where the issue is lying. Can a reviewer spot what in the changes made to RenderSVGRoot.cpp would cause repaints to areas outside of the overflowing area not to be performed?

Never mind that, the issue was pretty clear, overflow handling was already performed in RenderSVGRoot::layout() if shouldApplyViewportClip() was false and we were now resetting the overflow in all cases. Removing the new code for that purpose should fix things right up.

All the comments in this function are too “on the nose”, stating what the code below does and we don’t find those comments as valuable as comments saying things that the code does *not* say. They can be improved by focusing more on *why* the code is needed, and minimize stating what the code does. > Source/WebCore/rendering/svg/RenderSVGRoot.cpp:361 > + FloatRect contentRepaintRect = repaintRectInLocalCoordinates(); > + contentRepaintRect = m_localToBorderBoxTransform.mapRect(contentRepaintRect); Might read better as a single line. > Source/WebCore/rendering/svg/RenderSVGRoot.cpp:372 > + // The selectionRect can project outside of the overflowRect, so take their union > + // for repainting to avoid selection painting glitches. > + LayoutRect decoratedRepaintRect = unionRect(localSelectionRect(false), visualOverflowRect()); > + repaintRect.unite(decoratedRepaintRect); Why not two calls to repaintRect.unite instead? > Source/WebCore/rendering/svg/RenderSVGRoot.cpp:377 > + LayoutRect rect = enclosingIntRect(repaintRect); > + return RenderReplaced::computeRectForRepaint(rect, repaintContainer); Would read better without a local variable and on a single line.
