Not sure if its an update but finding audition to be a pain recently.
Editing etc is fine, however there are 2 things that are doing my head in.
1. Signal meter on the effects panel showing no signal so you don't know if you're clipping your outputs. If its hanging because of some background processing or something, atleast grey out...
2. Duel screen (i put my mixer on my Mac and use my external monitor to edit). For some reason when Audition is in focus, the Mac screen goes total black or white... can't see the mixer unless i launch another programme and event then when i click on the mixer the screen goes black again. I then have to fumble through quitting applications to start again.
Just me 🤔
I have seen the problem you list as your number 1. I actually raised it in a post here: https://community.adobe.com/t5/audition/more-of-an-quot-annoyance-quot-than-a-bug-but/td-p/11577176?... but no-one replied so I assumed it was only occurring for me.
It does only happen, sometimes, in Multitrack, not Waveform and I am on Windows so perhaps our two situations are slightly different.
I wonder if anyone else also experiences this, on either or both of MAC and Windows?
For your second item I have no idea; I use only one monitor so this clearly never happens for me!
I use Audition across three monitors (really!) and never have any trouble with anything blacking out, but that's on a PC. I suspect that this may be a Mac-only issue... but on the other hand, you might like to check and see if there are any updated video drivers for your Mac - that's the sort of issue that outdated ones can throw up.
