AMD Catalyst really weird screen issues

Hello, I'm experiencing some very weird issues since switching from the open source AMD driver to the closed source one (in order to increase performance).

My system specs are as follows:
- i7 5930k CPU
- 64GB Corsair DDR4
- EVGA x99 FTW motherboard
- 2 AMD R9 295x2 dual GPU cards
- 2 ASUS PB278Q 1440p monitors and one Acer B286HK 4K monitor
- Running Cinnamon with LightDM

Every time my system locks the screen, something like this happens to it:

The system is unusable until I SSH in and restart Cinnamon.

And when I resize or maximize certain windows, like my terminals or Firefox, certain ways, this happens to the window until I make it smaller again:

Also, when I play Minecraft and resize the window past a certain size, the window begins rapidly flickering in a very annoying manner.

I do not believe this is a hardware issue for various reasons:
- Works fine under Windows
- Works fine with open source drivers (aside from performance being too low for my liking)
- I can screenshot the artifacts, which means it's happening somewhere before it hits the GPU

How can I fix all of this?

If any more information is required, just ask, and I will do my best to provide it.

Sorry for the large images, this forum doesn't seem to support spoilers.
