Hello, I'm using Windows 10 and I have Radeon R7 370. If I re-install my graphic card and I don't restart my computer, alt-tabbing works just fine, the problem appears after the reboot. This is getting very annoying because my games are lagging. I found somewhere that there's a problem between the driver and Windows 10, about an Windows update, I installed that, worked just fine, until the next reboot. Help me out if you can, please.
