UI fixed, but now responds slower?

In an interview with Tri just after the league launched, Jonathan mentioned that they'd fixed a long standing bug that was making the UI run 3 times a second. With this fix I feel like the UI now responds slower but it's hard to explain what I mean as the UI "looks" to respond the same.

If there are interactables in the world such as loot or things to click like doors or waypoints, I feel like there's a delay between clicking and the game registering where you click. I've noticed a lot in this league that when I left click to pick up or interact with something and then instantly move my cursor away it'll use whatever I've got set to left click at the position where I had moved my cursor to rather than picking up/interacting with the UI I clicked on.

I will try and grab a video at some point with a mouse overlay to show what I mean, but it's been very noticable this league compared to any other leagues.
