That’s what bugs me, no.
Buffer like it was (1024).
I suspected codec, but my past sessions behave the same (as does the new one with MJPEG, as always).
Had 5.5 for a few productions now (-> used to work fine).
The current session doesn’t go into red on the VST CPU meter, and the onboard sound works flawlessly. The older mix sessions were medium heavy and dropout now. Used to work on them for hours (90 min doco mix, the current is just a few seconds long.)
Bodo thanks for the suggestions so far. Still has me puzzled this.
