Graphical anomalies

[schuffd]

Unplayable after the Comm Center script with the water.
Graphical interruptions. The game runs very fast and without error until this script thing at the comm center. Graphical anomalies

System: MacBook Pro late 2015, macOS Sierra, 16GB Ram, 1TB SDD, Iris Pro and ATI R9 with 2GB VRAM,
changing the graphic option has no effect, restart and reload no effect

The Weird thing is I can do screenshots but they look ok, when I take a video I can see the anomalies and a series shoot as well a little bit.

And seriously attamchent no bigger than 500KB ???? Every screenshot is much bigger
