This is a brand new macbook with very little installed running macOS 10.14.6 (18G1012).

For some reason the UI flickers between what looks like 2 different resolutions. You can see the first res during app launch. If I try to full screen using the in game button, the app will just hang and I have to force quit.

As you can see at the end, the system is running the game off of the Radeon and not the Intel.

Any ideas?

Thanks!
