Could you perhaps try different texture formats to see if that makes a difference. RG10B11, RGBA16F and RGBA32F.
Can you reproduce this on any engine examples?

This feels like a NaN gets introduced somewhere during rendering .. I fixed something similar here recently:
#7044

Once thing of note is the models themselves have a degenerate triangle https://sketchfab.com/3d-models/halo-mk-v-model-ff8a4e4f9d1f4fdeb3a1d887f6f70dae which could be related

yeah it does seem that rendering in sketchfab adds those strange lines too - and I suspect they generate some incorrect values somewhere during rendering.
