My connection's solid and it's a Realm I own, so there shouldn't be connection issues.
I found a similar graphic issue on Youtube and their solution was turning AA off entirely.
I'm also running W10 through a VM, so that might be the determinant factor (Xeon 6-core W3680, 24GB RAM, AMD 7950.)
My system:
Xeon W3680 3.33GHz / 24GB RAM / AMD Radeon 7950 3GB
Windows 10 Pro v. 1803
