Question / Help Window Capture Displays Black

[CyberSoul]

In OBS the "Window Capture (Xcomposite)" is only providing black boxes... They seem to be shaped correctly, meaning that smaller windows appear smaller when they have the red box around them but they are completely black. I don't know if anyone else is having this issue or not but if anyone has any ideas as to why, that would be nice. Thanks in advance.
Here's the log file:

I have this exact same issue. Running Ubuntu Mate 16.04 with the "Xorg AMD GPU Pro" driver.
