Random bugsplats in game ever since latest patch

Ever since the latest patch, my game has been bugsplatting more lately(especially on ARAM, less so on Summoners Rift)

I couldn't find any specific reasons, but maybe it could be this coincidence. Everytime I've crashed is always right after I visibly see someone flash on screen(not all the time, only sometimes)

Other information, I'm on a Mac, High Sierra
