Key presses sometimes not recognized when playing medivh

when i press my w, especially alt w, i occasionally get no response from the server. so its like i never pressed those buttons, leading to many frustrating deaths where i swear i got my alt w off before i died, but i guess i didnt. I do alt q on rehgar and never have an issue, which is why i think it is medivh specific.

Another issue i have is that i will also occasionally not go through his portal; i click directly on the hitbox, but nothing happens, so i have to press it repeatedly. I had the same exact issue in beta, but not in 1.0.

Is anyone else experiencing this issue? Or is this just another case of gitgud cuz i suck like a vacuum cleaner?
