ImageMosaic Footprint Draws Black Lines At Mosaic Boundaries

When using footprints with image mosaic plug-in with no inset turned on, the boundary between different images that got mosaicked together will show black lines. The black lines move at different zoom levels and if you zoom in far enough the black lines go away. If inset is turned on with a couple pixels, the black lines go away completely too at all zoom levels.

I have attached some images and associated shapefiles to reproduce the problem. Unfortunately, I can’t share the original image so I’ve altered the image into a binary image, but it can still reproduce the problem.

Note:
There are compression artifacts along the edges and that’s why I’m using footprints. I want to remove those compression artifacts by masking them out as transparent. The compression artifacts inside the footprints can be ignored.
