Fat Selection Outlines
In latest version of AI 24.2.1 on OS X - when I have two or more objects selected, one of them has a fat outline - irrespective of whether I have 'view outlines' mode selected or not. Pretty sure it's a bug. It's really annoying when I want to position multiple items optically using cursors and with outlines off. Because they aren't off.. Screenshot attached.
Definitely seems like a visual bug in Illustrator 24.2.1. When you directly click an object with the Selection Tool (Black Arrow) the edges are fine. However marquee selecting or selecting multiple objects results in these thick previews/edges, which makes alignment with smart guides even more frustrating than usual. It also gives the appearance of a double line or compound path as if the stroke has been expanded, which it has not been.
Thanks Egor - that fixed it! What a weird bug. Would never have found it -this has made my day.

Known bug with auto setting of key object.
99% fixed in 24.2.1
Please update and then manually once change the align mode with bottom-right drop-down menu in the Align panel to 'Align to Artboard'. This should most probably fix.
