Import issues

[mthoughdesigns]

I've recently had to reinstall GIMP on a fresh boot of my computer. When I important images that are larger than the canvas (i.e. I am working in layers and want to add something then resize) GIMP is automatically adding rows of dead pixels to the image. These images are seamless and do not have dead pixels/seams in the original. I have verified there are no additional pixels in the original image by opening it on its own, transforming it, and zooming in.

Does anyone know how to fix this? 

Thank you.
