Well, the clipping is required by design. That said, I agree using QML
clipping there is not good enough and needs to be improved. Back then
when the spread was implemented, MirSurfaceItem didn't support cropping
yet, so this way of clipping had to be used.

The solution for this bug is to move to MirSurfaceItem's surface
cropping mechanism and drop the QML based clipping.

Title:
  spread delegates are using clipping

Status in unity8 package in Ubuntu:
  New

Bug description:
  It appears that app windows are turning on clipping when the spread is
  opened. This is really inefficient graphically because it is a
  transformed rectangle and so Qt falls back to stencil-based clipping.
  We should avoid clipping in this case at all cost
