I cannot answer your technical question, but please
keep in mind that if
you are using any real-time audio applications, such as those that use Jack,
then switching desktops while doing important audio things will cause clicks
and pops in your audio stream.
In a properly tuned system, I don't think switching between virtual
desktops in the window manager should have any impact on a realtime
priority Jack. Nothing special happens here but a bit more X11
redrawing activity.
Changing to one of the linux *console* virtual terminals from
X is a different story, that has documented high probability of
overrun.
