Panorama contains horizontal line artefacts

[Georg Elsner]

I made a mosaic of a church floor, it contains 38 jpeg images, each about 5 MByte. This results in a 800 MB LZW TIFF. In the lower part of the TIFF I have two lines (about 5 pixel height) of wrong picture information (mosaic of black pixels and pixels of wrong colors. The original pictures had been cropped and masked. These lines begin on the left border and extend to the middle of the image, roughly. They are not of the same length. Perhaps they coincidence with borders of the original images. Even if I switch to jpeg output format, the error lines do not vanish.

This is an enblend bug that has been reported several times before but there still isn't a fix. It only appears with very large panoramas.

I've never seen it myself, but apparently it is related to the enblend image cache, you should be able to workaround the problem adjusting the enblend -m parameter.
