------- Comment #6 from macdome at opendarwin.org  2006-03-04 14:28 PDT -------
It is definitely this line of code at fault:

render_layer.cpp:

static bool mustExamineRenderer(RenderObject* renderer)
{
    if (renderer->isCanvas() || renderer->isRoot() || renderer->isInlineFlow())
        return true;

layers of inline flows are *always* repainted.  Not good :(  We'd have to
change this check to actually check against their bounds.
