@jeff Jeff, only is a later post- you know best, and I’ll butt out after this , but the initial post, at the very top, seems to me not concerned with the ambiguous selection…it sounds at least somewhat like some other reports we’ve been seeing here and on Apoio. ( apoio conversation 322140 for example, and Amd radeon hd 8670m open gl issue - #9 by clement which is also specifically a 4 viewport glitch with an AMD card.
I’ll leave you to it now…
