Weird button link behavior in safari

Hello, I am getting some strange button behavior in safari when the links are rolled over. It goes from the light text to extra light and back to light again really erratically. I believe it is during the rollover transition which I have set to transparency only. I never used to have any issues like this but recently I have been having a fair amount of bugs and strange behavior with the transitions. I think there may be something that you guys tweaked in that section that is causing this strange behavior.

Looks like you fixed it? Checked it in Chrome + Safari. Looks fine.
