Bushes?

I'm sure many of you have noticed, but I haven't seen many questions about it (maybe I'm just blind) but the bushes in the current SR are extremely glitchy and unpredictable. For example, if you have a teammate in a bush and an enemy walks into that bush that your teammate is standing in you will often lose vision of that enemy for a split second, often messing up navigation and causing a negative outcome which otherwise should have been good. There are also problems with not being able to see ability animations in a bush you are currently standing in as well as some abilities not giving vision when they should (I've often not been given vision from Cassio's W after placing it in a bush.) So I was wondering if Riot has been working on fixing the major problems with the new bushes, because in the promo they said they're keeping everything working the same way when it comes to lane sizes, flashing walls and bushes, which worried me a little.
