After downloading MacOS High Sierra, can't minimize client and have had 4 game crashes in 7 games

I have yet been able to minimize the client but the crashes are the worst. The game just disappears and brings me to a windowed client asking me to reconnect. It lets me play the whole game after that but every other game around the 2 minute mark the client crashes. This happened after I downloaded High Sierra so not sure if they are related.
