I have an issue with blender 2.8 BETA. In viewport I can see materials I made in 2.79 and switch among them but I can't see any changes I make in 2.8. I can't create any new materials using nodes to be seen in viewport. All the changes CAN BE SEEN in rendered picture. I can see changes in material when I turn off "USE NODES"
I have Mcbook Pro 13-inch, 2016, 2,9 GHz Intel Core i5,Intel Iris Graphics 550
I have tested it on PC and it worked perfectly, Thank you
