¹) if the zoom level is >= 140% (Debian Testing, KDE, Radeon RX480, Xorg, 2560x1440).

This is caused by bug 1458968

It looks like this exposed an existing bug in WebRender. If the contents of a blob image go out of view WebRender won't remember them and it only asks for the newly invalid region. i.e. If we don't clip our rendering to the dirty rect the items don't go away.
