    <thetext>run-webkit-tests -p fast/repaint/fixed.html
shows the failure.

This is a regression, so technically p1, but I feel bad marking it such. ;)</thetext>

    <thetext>The repaint that does not cover the green square is coming out of RenderLayer::updateLayerPositions(), painting m_repaintRect which has the pre-scroll location, and happens via the call to layout() from externalRepresentation().

Repaints of fixed position elements when the page has not just scrolled are not too large, so we&apos;re not over-painting in the common case.</thetext>

    <thetext>I looked at the different outputs of fast/repaint/fixed.html and they look fine on Chromium and Mac. Gtk has a bad image checked-in as it does not seem to implement createBitmapContextFromWebView properly.</thetext>
