New camera problem

My new DBK618 camera has a problem with gridlines at 60 fps. I posted about this over in the Imaging Source forum a couple of weeks ago, and they are (still) looking into the problem. One of the big selling points of this camera is its (supposed) 60 fps capability without artefacts. The model it surpasses, the DBK21, was also supposed to support 60 fps, but eventually it turned out that it produced a "ring"-artefact at this frame rate. It is therefore disappointing that once again this new model does not function properly at 60 fps. It is also surprising that nobody else have reported this problem before, as the camera has been on the market for more than 6 months. After I reported my problem at the forum, a couple of other owners of the camera have reported the same problem. Nevertheless, the results so far (at 30 fps) seem to be significantly better than my old DBK21. 

Below is Mars from a 60 fps capture (sharpened and resized by 2X). It does not matter which DeBayer method I use, the gridlines are always there. Multipoint alignment will partially solve/mask the problem, probably because different parts of the planet are moved around a little relative to each other, and blended in a way that hides seams and averages out some of the gridlines. Still, it is not a good solution.
