Actions/abilities are registered and occuring but not displayed on screen

I started noticing the issue with champions with gap closers, renekton's slice and dice, zed's shadow, corki's flight, ez's blink, reksai's tunnel, etc. but it is happening in other random fights as well. I can hear the actions happening, like grunts from champions and blades swinging, but it doesn't show the action's for a few seconds. On one occasion I was evelyn fighting a volibear. After spamming "hate spikes" a few times it stopped showing me animations and on my screen it just showed he and I standing still. I could hear the animations going so i kept spamming. After a few seconds of fighting it indicated on the side of my screen that I had killed volibear and then I could see myself moving again/ability animations. In a fight where no one moves it's not as big of a deal but this is really inconvenient and noticeable when I need to predict the direction of ez's blink or even see where zed's shadow is at and it isn't displayed for a couple seconds. It usually lasts from 2-4 seconds. While this is going on my game shows that it's running at a steady 144fps and 71ms. I've checked my own system's performance and internet connection and both appear to be running correctly.
