Syndra In Arams & Fog of war
Syndras ultimate right after being used makes your frames jump all over the place. Your entire screen after each time its used becomes shaky.
Another aram bug is going instantly invisible (into fog of war) when entering a bush after attacking someone. So people literally attack you and walk in a bush and youre either forced to wait for them to come out or face check. The timer is a lot longer in summoners rift, i think it needs to be updated for arams too.
