Hey @castano .

I am seeing this with the latest NVTT:

image

The color isn't premultipled and the checkerboard there is an area of alpha (~25). The left image is process via another DXT1 compressor... the right is NVTT using DXT1a and alpha mode set to transparency no dithering.

Any ideas as to what i could be seeing there and a hit as to where to start debugging it?
