You rendered with anti-aliasing turned on, right?

Try without. Also make sure you set mosaic preview end size to 2.

During mosaic preview, results from each pass are re-used for the next one.
Likewise, the final pass re-uses all results from the mosaic preview passes if
possible (that is, if anti-aliasing and focal blur are off, and - to keep
implementation simple - the preview was done right down to size 2).

As it seems, the data for all the rightmost blocks gathered during each preview
pass is discarded for some reason (or overwritten with black).
