Lots of visual bugs

Noticed there are a lot of visual bugs lately and its kinda annoying. For example Aery is extremely glitchy. I can't tell where Aery is its just glitch out side to side. My Aery and enemy's Aery. How can I tell when Aery returns other than the little icon above your skills? My friend also has noticed seeing a teammate visually standing somewhere random but they aren't actually there. Like their champion is just...there. Also noticed Kha'zix evolution glitches on streams where theres white boxes on the screen whenever his ult is upgraded or something.
