When I open a YouTube link in Safari under virtual Snow Leopard, it stutters and falters. The video is often not visible. The same URL in native OS X plays fine. Any thoughts?
Sounds like the same problem I'm seeing. If I keep the old Parallels drivers (i.e. don't allow new drivers to be installed), it still works. https://forum.parallels.com/threads...th-parallels-16-1-1-using-new-drivers.351686/
