>>> distorm3.Decompose(0, "66 48 0f 6e c2".replace(" ", "").decode('hex'), 2)
[<distorm3.Instruction object at 0x0000000002691BE0>]
>>> print _[0]
MOVQ XMM0, RDX
>>>

Looks good to me, let me know if you still see this problem with latest version.

Also using your way with:
str(distorm3.Decompose(0x1056bf5a, '66480f6ec2'.decode('hex'), 2)[0])
Yielded same correct result.
