Blue Squares/Invisible spells

This issue started up about 3 months ago. 9 out of 10 games I play, colorblind mode manages to turn itself on or something in-game doesn't load properly and shows up as a huge blue square, namely champions (once had a game where the entire enemy team was blue squares so I had no idea who was who), spells or attacks (it's an eyesore when cannon minions shoot giant ass blue squares everywhere), or sometimes spells and attacks just don't show. But that happens in about 3 of 10 games, still, enough where it's gamebreaking for me. I played a game as lux where I couldn't see my e after sending it out and the only way I knew I stunned someone with my q is if they stopped moving. I left the game and came back and my lane partner's icon was a giant blue square, go figure. It wasn't a huge deal a few months ago but now there's something wrong in nearly every single game, whether it be the blue square placements or invisible spells. Has anyone else been experiencing this or is it just me? My husband plays on a separate computer and has these issues as well, if that matters.
