I've used Macosaix in the past, with very nice results.

This new release has a serious bug for me: the nearly white areas are filled with dark tiles.
The borders of the white area are ok, but in the centre the tiles are dark.
In the same way, nearly black areas are filled with light tiles, giving a weird effect on shadows.

I tried many different images, formats, tiles combinations, number and cropping settings with no success.

I wrote the developer, who kindly replied me and sent me a new beta release, which unfortunately has the same problem.
From that moment, I had no more news... he didn't reply to my mails anymore.

Anyone has the same problem with Macosaix?
