Have the same issue, Tried to install my own system as thought I would give antergos a try.
Already switched my daughters from Mageia as hers has an AMD 290x. (Mageia built mesa13 with llvm 3.8 )
My system specs
GTX 1080 fe
Have tried both 2016.11.20 iso and 17.1 iso. Both have the same problem
Would be nice to know the OP’s specs/info
GTX MSI 1070
