Some other things I have seen only since patch 8 launch, which I'll report via the bug reporting mechanism when I get a free minute to create saves:
(1) There is a conversation point that invokes on the first character that turns south just after going past the Baldur's Mouth building on the main street from the Basilisk Gate. The conversation never happens, and the character is effectively soft-locked from that point on -- unselectable and unmovable, just sitting there in conversation mode for a conversation that never completes. (Other characters are also limited in what they can do.) I've had to avoid going through that side-street because of it.
(2) The screen often goes completely black after transitions to a new area (either via portal, or for example in the Ramizith Tower basement as you go through certain doors), though mouse highlighting still works. Minimizing BG3 with the Windows key and then maximizing it again is the workaround. This only seems to be happening in Act 3 -- I didn't see it in Act 2 despite being on patch 8 during it. (The first time I saw it was when transporting back to the Rivington Portal from the Circus.)
There are some other weirdnesses, such as a static screech that sometimes happens when selecting a different party member, but they are not blockers.
