I, like you have used this technique for a long time. (i started on Avid in 95, and that was how i learnt to use audio on the timeline…still do it to this day)
I am now running box on 8.5, one on 8.6 and haven’t seen an issue.
Are you hearing the pop after you add a dissolve?
I will occasionally hear a pop on an audio edit if you are not at a 0 point crossing in the audio, but usually a 1 frame dissolve will fix that.
do you hear a pop if you do an add edit, but don’t adjust levels on either side?
