Two examples that immediately come to mind are trying to fight in World of Warcraft when underwater (where I had no eff'ing clue where exactly the enemy actually was, relative to my character) and overly flashy effects in games, often MOBAs (where they were taken so overboard to where I had no idea what was even happening on the screen).
I'm surprised people put up with either of these. I found both of them in and of themselves really frustrating and detracting from the fun of just playing the game.
I'll give an affectionate shoutout to Transistor; one of the mechanics is having to deal with paparazzi-like monsters that are just flying cameras whose difficulty is in obscuring your screen with flattering action shots of the protagonist. Lazy, but clever and adorable!
