Smart object gray layer at top of file causes blocks when working

(Re-posting since Adobe can't seem to transfer my Community activity from my company account to my personal account.)

When working on files with a grain layer (gray layer with noise and g.blur smart filters) at the top of the file I often get gray blocks when I try doing any sort of pixel based adjustments--paint, clone, heal etc--below. This has been going on for years.

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Photoshop forum so that proper help can be offered.
