I don't know what's happening. I'll have stuff open and I'll get weird white spots on my screen. It goes away when I click on it. How can I fix it?

It's not white spots. These are screen wipeouts that happen in many systems when the processor is slow to handle graphics memory.
For example, if you drag a window, the space behind it will turn white.
I recommend upgrading your processor and/or RAM or not doing heavy graphic-oriented multitasking.

As you're using Kali Linux, I think it'll be appropriate to consider with their support. For example, there's this group on Facebook that my cousin showed me (and he's an active part of): here's the link (you'll need a Facebook account). It's more Windows-friendly in graphics interface, so there may be things we don't understand. Jun 15, 2014 at 13:32

I think it is problem around your currently installed drivers. By me your system capable to do not use fallback mode at all despite the fact that fallback is more hybrid and flexible. Fallback mode uses Ubuntu-community driver. Though your system have adequate power to use Bumblebee Nvidia driver.
