Photoshop :: CS6 Offset Filter Not Working As Expected

I've been using the offset filter for years to create seamless patterns with predictable results - I choose "Wrap around" and when I enter the distance the parts of the image that go off one side show up on the opposite side.Now, with CS6, sometimes it works as expected and sometimes parts of the image go missing when (if) it shows up on the other side. I've discovered that when this happens if I go to Image - reveal all that often times those lost pixels are outside of the viewable canvas. However, sometimes reveal all doesn't show anything new and the pixels have just been lost.I know there are not extra pixels outside the canvas are before I run the filter so I don't understand how this is happening.

I have found is to select all and crop the image between every offset. Sometimes I'm offsetting 20-30 layers in a row (because you can't apply a filter to multiple layers at once, so annoying). Otherwise, if I'm not careful after I've offset everything I go to check the pattern and realize i lost parts of my image.
