Fix for T101438
Clamping the mip seems to always set it to 9.0.
I couldn't find an alternative way to avoid triggering the error (ie. min(mip, 9.0)).
In any case, the results with this patch applied look the same to the (correct) ones on AMD.
And, since clamping the max mip to a hardcoded value could result in resolution-depended behavior, I guess disabling the clamp should be ok anyway.
