(fixed 1516) Small rendering error in newst build 1414

[PIGSgrame]

There's a small rendering issue with this PDF file (http://www.datumsrechner.de/FeiertageSchweiz.pdf): Some of the colored table cells have a white vertical line inside when the document is viewed at 100% size. In case this is not reproduceable on every computer, here is a small cutout as it looks like on my PC:

It only happens in the newest build 1414. Before this release, everything was rendered fine.

Thanks. I can reproduce it and will come back to you with solutions.

With build 1516, it works again as it did before the 1414 update. Thanks!
