This is a improved version ofa73cd88f0cThe old commit was reverted in552dd18696The new version only paints an element into a new layer if background blend modes other than normal are used. The rasterization performance of most websites should therefore not suffer. Co-Authored-By: Alexander Kalenik <kalenik.aliaksandr@gmail.com>
