More Projector shader trouble

Compare the render result of the upper torus (projection applied to directly in the tag) and the lower one (projection applied to via Projector shader).
Trying to get a reasonable result, or a result at all, fails with Cubic, Spatial or Flat (set in the Projector shader node). The rest is more or (mostly) less reliable.

Hello,

this is already identified in (Internal ID=657744340), but thank you for reporting. We are thinking of a way to handle Projector issues as the underlying cause is a hefty one.

Thanks,
Jan

Fingers crossed for a Corona Projector node.
