Size of minions and champs on PBE compared to live

Not sure if this is a bug, but on PBE minions and champs appear very small compared to how they look on live (NA). Conversely, terrain and turrets look rather large. I have tried to find something to change the scaling in the settings, but I couldn't find anything. Does anyone else have this problem? It makes it extremely difficult to last hit minions since their health bars are much smaller, and it makes it difficult to target champs or minions since I can't seem to click directly on them because they are small and fast.
