Elevated terrain is still a problem

I was watching a LCS highlight video, and Bard got a 5 man ult. I thought to myself "Wow i didnt even see that" Then i realized I DIDNT SEE IT, i went back and rewatched it and noticed only part of 1 edge of the ult is visible and the rest is caught on the elevated terrain.

I saw another instance of this while playing darius and walking into the enemy base whilst qing, and also in URF when you throw sivirs Q in fountain is becomes invisible for some of the fountain.

I know its a known issue which is why im not posting this in "Report a Bug" but just clarifying that it still causes issues frequently.
