Interesting. There seems to be some memory corruption going on.

It seems the cause is that the picture's resolution is not a multiple of 4 (a known limitation of ETC2).

Betsy should internally upscale the image from 3802x2517 to 3804x2520

It seems it was two bugs in one:

  1. Resolutions with non-multiple of 4 were broken.
  2. On Windows the command line parser was broken.

I'll be uploading a new binary release today

Done

Thanks for the report!

This is not exactly the test case but it works on Fedora 33.

PS. Do you know how to open KTX files for BC5 and BC6?

Unfortunately I don't. Most viewers out there (all the ones I tried) are horribly working and only support a small subset of formats.

I gave up on that and debugged the output on RenderDoc (add '--renderdoc' to command line)
