It seems we have to go through these raft of bugs every time there is a new release. Sigh. Parallels 16 was working nicely. Running on a Mac Pro 2019 with 16 cores, and a Window 10 VM with 64MB RAM and 22 virtual cores. Mouse cursor sometimes gets stuck on last cursor Generally poor graphics performance Full screen YouTube can hang for a few seconds) Playback isn't very smooth Scrolling text in editor windows slow/jumpy Sometimes get crackling sound from VM audio after switching to host OS Is it possible to downgrade? This is not at all acceptable.
