The only settings I've changed between the two are the render resolution -- from rending at the preview window size to rendering at 3000x3000.

No other settings were changed.

I'm attaching 3 pix. One is the original one -- which appears as it should. The 2nd is a reduced version of the 3k render. The 3rd is that reduction with the error areas marked -- most is below the white line near the bottom, but there's also a small "blocky" area that I've circled.

Hope this clarifies and helps you help me.

Thanks.
