View in context: https://bugs.webkit.org/attachment.cgi?id=104300&action=review > Source/WebCore/rendering/RenderBox.cpp:3254 > - if (child->hasSelfPaintingLayer() || hasOverflowClip()) > + if (isRenderView() || hasOverflowClip()) This is wrong. You can't add in overflow from a self-painting layer. That will just lead to overpainting.

Is it something we are pursuing now or we can close this bug or mark it as "RESOLVED LATER"? Thanks!
