Since i upgraded my old GPU (GTX 660) to a RX480 i have screen tearing while i scroll webpages or watch videos on youtube or with any videoplayers. In games i always activate vsync but on desktop it seems it don't work. I have the newest drivers installed and everything else works perfectly. But the screen tearing is kind of annoying so maybe someone can help me to get rid of it. Thanks.
Edit: I think it has to do with Radeon global settings: Power efficiency turned on and/or frame rate target control turned on.
