The graphic glitches are significant for myself and my two other party members. We've lost a handful of games due to these issues occurring mid game.
I too would really appreciate knowing if the Xbox patch will include a fix for this.
Rest of the update looks amazing!
There is sadly no fix for that particular glitch in this update, but we are actively working to fix it. It will likely need an update of the actual underlying Unreal Engine, so we need to move carefully - updating the engine usually brings a lot of new issues with it.
