I have an AMD R7 M360 in a Dell Latitude. The primary GPU is integrated with the Intel CPU. If I disable the primary GPU and use only the AMD GPU, apps crash when they try to create an OpenGL Window.
I suspect bad AMD drivers.
Driver v 17.11.1
CPU : Intel i7-6600U
I suggest leaving the CPU graphics available
The BIOS should have an option to set the Radeon graphics as default
