I’m running into this too. For example, if I draw a rectangle on top of some background layers, and then try to insert text on top of the rectangle, the text input tool is highlighting the text layers in the background. In the screenshot, I drew the grey rectangle, and have the text tool selected…you can see that when I hover, it’s highlighting layers behind the rectangle. I figured this might have something to do with auto-layout, but still shows up if the background layers aren’t in auto-layout frames
