I am using QtWebkit 5.1.0 on Windows 7 x64. Crash is located here: void RenderView::paint(PaintInfo& paintInfo, const LayoutPoint& paintOffset) { // If we ever require layout but receive a paint anyway, something has gone horribly wrong. ASSERT(!needsLayout()); <---Assert failure here. // RenderViews should never be called to paint with an offset not on device pixels. ASSERT(LayoutPoint(IntPoint(paintOffset.x(), paintOffset.y())) == paintOffset); // This avoids painting garbage between columns if there is a column gap. if (m_frameView && m_frameView->pagination().mode != Pagination::Unpaginated) paintInfo.context->fillRect(paintInfo.rect, m_frameView->baseBackgroundColor(), ColorSpaceDeviceRGB); paintObject(paintInfo, paintOffset); }

I cannot reproduce this on Mac ToT. Closing, as Qt port has been removed from WebKit.
But while loading http://www.kohls.com and then scrolling for somtime crash is happening on the latest webkit.. Alexey can you please check again ..
Please attach a crash log if you can reproduce this.
hi Alexey, When I load http://www.kohls.com in my visual studio latest code build then I am getting crash and CrashReport.dmp file get generated. But I don't know how to convert this crashReport.dmp file to callstack..But it is happening everytime.
