[GAME] The game goes to 00 fps every two seconds in game.

I dont know how or why, but the game just hits 0 frames every 2 seconds. It has occurred only once and at the very start of the game. The game was working well for me all day so I'm not sure what caused this. I play on macOS Mojave on a macbookpro 2016 model. This game is different from the other ones earlier today since this was one in which I queued up with another player. The champs and skins used in this game are as follows:

• Championship Zed

• Eternal Sword Yi

• High Noon Lucian

• Dark Star Thresh

• Veigar

• Warlord Shen

• Cosmic Defender Xin Zhao

• Pulsefire Caitlyn

• Dragonslayer Braum

• Ryze

Could be caused by any of these champs/skins or hardware but I have no clue. There were no other programs running in the background.
