I think I have problems between AMD Radeon R5 M430 and INTEL HD GRAPHICS 520 on a Notebook HP 15-ay065nl. Sometimes, when I start an app, it's windows doesn't appear on top, but I must minimize the window on top to see it.
Not an AMD problem from your limited description, more likely to be Windows/App.settings.
