Every afternoon I unplug my rMBP for the day and don’t use it again generally until the next morning. Every morning, the current UE4 project wakes up seemingly ok, but in fact unable to be used normally. Basically upon waking, I am unable to look around with the mouse. Instead it simply slides left/right when I attempt to look left/right. Quitting and relaunching seems to be the only fix.
Only thing of major note is that I’m using a KVM to connect a keyboard and mouse during the day. But I can disconnect/reconnect them while the Mac is awake and it seems to behave normally. It is only after sleeping/waking that mouse navigation is broken again.
