Scene Editor Lag on Mac (Intel and Silicon)

I’ve been getting major lag in the scene editor on both Mac Intel and M3 hardware. The scene only consists of multiple buttons and as I create more, the lag gets worse. It’s to the point where simply trying to resize a button is incredibly tedious.

I’m using the menu buttons from the Asset Store.

Any suggestions on what to check or how to debug? The rest of the program runs fine.
