Studio developer page not performant with many places visible

When viewing studio pages with many games displayed, there’s a lot of frame drop and input latency on animations. For example: the “settings” button that’s displayed when you hover over a place takes a very long time to show up (or disappear) depending on how many places are visible. Any input sent to studio seems to be delayed.

I do not know when this started happening
