I suppose it's the problem here, because the pixels you point to are near a black and a light grey lines.A typical compression in dds (I don't remember which ones) accepts only 8 colors in each 4x4pixels square, and the interval between these 8 colors are constant. This can create the kind of artefacts you are seeing.
GIMP 3.2 soon to be published can export in BC7 format. Try it on the RC3, or wait until it's released, maybe it's better (I don't know its characteristics).
Here a (technical) website about those formats: http://sv-journal.org/2014-1/06/en/index.php?lang=en
Hi. Thanks for reply.
I don't need other format. My game engine accept only .dds file, so I need dds.
Friend told me that he doesn't had that problems with Photoshop and Intel DDS exporter.
