Using ImageMagick 7.0.8-68 Q16 x64 HDRI on Windows 10. With this release the "-compose lighten" method seems to be broken. With previous versions this command would place the built-in "granite:" image over the built-in "wizard:", and only partially lighten the 128x128 area in the center.
With the current version – 7.0.8-68 – when using the compose method "lighten", any image composited over another will completely white out the area where the source image is placed on the destination. In other words, the example command leaves a 100% white square in the center of the "wizard:" image.

The issue doesn't occur with the recent release of IMv6 – ImageMagick 6.9.10-68 HDRI – or with previous HDRI releases of IMv7.

I can confirm the same behavior with the same versions as GeeMack on Mac OSX Sierra.

It seems to work fine on v7.0.8-64 on Windows 8.1.

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.
