Hi, feel free to close this issue given that it's most-likely an emulation-related problem. It might help some other people with the same issue though.
I tried to compress the following image (arco_frente.png from San Miguel from McGuire's Computer Graphics Archive) with this command:
wine texconv.exe arco_frente.png -srgb -bc x -f BC7_UNORM_SRGB -fixbc4x4 -y
.It displays (both in-engine and in renderdoc) with a red streak of bad blocks in the first mip level:
This is the same for all images that I've run
texconv.exe
on with this particular setting, although I haven't extensively tested it.Luckily, I don't get this issue at all when using
-nogpu
so that's a good-enough solution for now.I got the texconv.exe binary from here: https://github.com/Microsoft/DirectXTex/wiki/Texconv.

Texconv listed adapter: Intel(R) HD Graphics 4000
