Replays Basically Nonfunctional

Last 2 patches, there have been a TON of visual issues with replays (including weird kayn position switches and looking like an ally). I've had invisible dragons and barons when on one side of vision. There are so many problems that I'm not even sure what to focus on. It used to be more or less fine in the past and this is on a new computer with a fresh install. I checked it for corruption and it was fine. I just hope you guys are aware.
