Is Fedora for developers or what?

We want to ditch extremely useful, ground-breaking features because of
"tearing" when scrolling in a browser window? [I do *not* see any of
those issues incidentally -- maybe you want to check your set-up and
make sure you're not using non-free drivers]

You have no evidence anyway that this tearing and high CPU load that
you are seeing is caused by network transparency.

It's pretty unlikely since X messages are passed from application to
server using shared memory in the local case, and how exactly did you
expect the app to communicate with a Wayland server except using the
precise same mechanisms?  There are only a limited number of ways that
two processes on a Unix machine can talk to each other.
