Thank you for your very knowledgeable input, really appreciate it.

I am wondering why I am the first to notice this particular corner
case. Is this perhaps because X+armada plugin allocate a huge bitmap
that fits all displays, and other software frameworks do not? Are
people on i.MX6 mostly using X or Wayland? If Wayland allocates a
separate bitmap for each display, this PRE bug will of course never
show up...
