Making xpra vsync-aware should be possible but I am not sure how hard it
would be. (you will not be able to use xpra with another compositor)
OTOH, the server side would require setting the backing pixel data as
copy-on-write on each vsync, and always using the previous copy.
For the client side, I'm not sure what can/needs-to be done.

It does get used, it provides the low-level window management bits.

Yes.

I'm not sure what you mean by "isolate".
