I helped implement BC7 export support in GIMP, so I'll take a look. So far I haven't been able to replicate - it all works fine for me. Unfortunately, the attachements you posted are not visible; could you report (or post them on the tracker)?
Hi!
I did some more tests and was able to clearly reproduce it and - by the way - found a workaround. The issue happens when there is an addidtional channel beside the RGB (see picture below) once you delete that one the export to DDS (BC7 with MipMaps, ...) is working again:
Here is the error message:
Shall I do a bug report?
