Issue Description

I’m using the frameit feature of Fastlane to generate my screenshots, frame them into a device and to put the device on a single colored background and add some text. Eventually it’s supposed to look like this:

I’m taking 4 screenshots in total, each one is supposed to be placed on a different color. Instead the first 3 screenshots are placed on the yellow background and the 4th image is placed on the brown background. This doesn’t apply to iPhone screenshot, on these everything just works, but I’m struggeling on iPads. On different iPads different backgrounds are chosen, but not the correct ones. The only indication is given by the Magick warnings, but I’m not sure how to debug these.

As background images I use these 4:
