Whenever the web block encapsulates the entire screen's widgets, for some users scrolling on that page flickers wildly.  However when we break everything up and add lots of web blocks with a few widgets in each, scrolling works fine.  But we don't want to do that as the text overlaps making it hard to read, so we want a single PanZoom for the entire screen.

Does anyone know why this might be happening and how to fix it please?
