MacOS Siera Image Distortion Bug [Game]

After the recent update for MacOS whenever I start a game now the image will heavily distort on the loading screen. I will get screen tearing that pulses down the screen repeatedly on 1 inch bars horizontally. This appears to be a HUD bug. When the game begins the play space is fine but the menus, map, and ability rack is all distorted in sequence. This is easily remedied by command tabbing out and back in. Tech Specs: Macbook Pro 15 inch 2.5GHz quad-core Intel Core i7 Turbo Boost up to 3.7GHz 16GB 1600MHz memory Intel Iris Pro Graphics AMD Radeon R9 M370X with 2GB GDDR5 memory

Steps to reproduce:

1. launch the client
2. create game
3. launch into game
4. distortion should happen right away in loading screen
5. Distortion continues on in game menus but not the internal game space
