Lenovo Y700 AMD Graphics Card Screen Tear/Flicker

Hey guys, I need help! I have a Lenovo y700-14ISK with a dedicated AMD Radeon R9 M375 graphics card. Everything runs fine when I'm not gaming but when a program uses the high performance graphics card my screen tears and flickers like mad(see youtube link). As soon as I switch out of the window, the screen tearing stops. I've tried a combination of changing Vsync and settings with no avail. Thus I think is it something wrong with the Radeon M375 graphics card, maybe with the connection?

Edit: Radeon driver up to date, BIOS up to date, OS windows 10
