Image broken with 4 monitors, but everything works with 1,2 or 3

I have a macbook pro 2015 set up running linux natively. Through this I have 3 monitors plugged in.

2x Thunderbolt 1x HDMI 1x Laptop Monitor.

If I have 3 monitors the image is as expected. However whenever I plug in a new monitor to equal 4 monitors active in total, the "tearing" starts to play up.

What I find even more confusing is that the background image is perfectly fine and the only issue seems to be the windows/taskbar etc.
