Home screen won't load because of Dual Graphics Card

The home screen wont load one website stated Minecraft tends to not work or have a bug where it will not work on laptops or computers with duel graphics card and my laptop has one which is what I play on. The graphics card that doesn't works is the: Radeon(TM) 520 whereas the graphics card that works is the: AMD Radeon(TM) R5 Graphics. The one that works is the one I changed to recently when Minecraft didn't open but now Minecraft doesn't run as well with keys being delayed and double tapping buttons to do actions like sprint are a nightmare to activate.
