Fiddling with color balance seems a good way to cause this. I've also seen it when fiddling with white balance. The preview in the navigation panel shows correct color, while the full image view shows the weird colors. I can see this when the view is "fit to screen" or 100%. In the later case, the image looks suspiciously like a CFA problem. See https://i.imgur.com/NG4G1y6.jpg. This is with OpenCL disabled and an X-Trans image. Will keep looking into this.
