Pings drop frames to 0

Not exactly sure how replicatable this is, but for my client, it appears pings will drop framerate to 0 until the ping disappears. This only applies to allied pings, my own pings are fine for some reason. Really frustrating to deal with, though, when every time an ally uses a cannon I suddenly can't play the game for ~5 seconds. It's also unpredictable; it happened while I was playing Pyke and Kai'Sa in ARURF, but no issue at all with heimerdinger (both pyke and heimerdinger games were on minimum graphical settings)
