Hi,
I'm slightly confused. Could you clarify for me?

If you mean that your 1.8 project has an image with "no stretch" applied and that shows as a grey box in 1.9, then yes this is known and there's an issue reported. I understand it has to do with there being some significant changes to the way vectors are handled in the new version. Once you've stretched the image in 1.9, you should be able to put it back to "no stretch" and still see it. http://hub.qgis.org/issues/6809.

If you mean that your 1.8 project has an image which "already has a stretch" applied that shows as a grey box in 1.9 then I think that's new. 
I couldn't see this happening on a mac using 0005467 this morning, but will also check on a win7 box later.
