Using ImageMagick 7.0.7-37 Q16 x64 HDRI with Windows 10 and running this command...
Produces this image...



The top approximately 1% of the image is a gradient from white to black, and everything below that is pure black. This image is 2000x2000, and the gradient covers about the top 20 pixels. If I make the image 100x100, only the top single row will be white, and the remainder of the image is black.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ https://www.imagemagick.org/download/beta/ by sometime tomorrow.

If it's of any help, the same happens in Manjaro Linux. I'm using ImageMagick 7.0.7-37 Q16 x86_64 2018-05-30.

It is fixed in IM 7.0.7.38
