Screen freezes upon death (Mac client)

Server: NA Type of Bug: In Game Bug Description: When you die on the mac client, the game temporarily freezes (1-3 seconds) rendering "after-death champs" fairly useless. Steps to reproduce: Works with any champ. Play on mac client, and be killed. Expected result: Death screen appears as your champ dies Observed result: Game freezes as the auto/skillshot hits you, stays on that screen for 1-3 seconds. Reproduction rate: (7/10) System specs: MacBook Pro, 1.9 GHz Intel Core i7 processor, 8 GB 1600 MHz DDR3 memory, Intel HD Graphics 4000 1024 MB

I could probably make a video of the bug if necessary. It happens every game. This isn't a huge issue normally, as the freeze only occurs once you are dead. However, with "after-death" champs (Karthus, Sion) it makes it almost impossible to use these champs.
