Help! Screen glitching, flashing bars, shutting off! 13" Macbook, Razer X(RX580)  

Hello!

I just bought a used EGPU. It's a Razer X with RX 580.

I plugged it in and everything is working fine, but when I start up a game, the screen starts switching off, white flashing bars run horizontally, and the sound cuts in and out. Whats going on???

I have ruled out that the TB3 cable, and DisplayPort as issues.

I also did a benchmark: the card scored around what everybody else was scoring, only issue was that the screen was glitching out while the benchmark was running. 

I have attached a video of the issue. THANK YOU!!!
