This doesn't break anything, but the current version of cephfs-top
cannot accommodate great number of clients. The workaround is to limit
the number of clients (if that's possible) or reduce the terminal
zoom/font size to accommodate 100 clients.
We have a tracker [1] to implement the limit also.

Yes, `ceph fs perf stats` works.
Reverting to older versions I get "exception: addwstr() returned ERR"
If I manually set self.height, self.width to something large in
refresh_window_size I can see some data, but there is no way to
scroll, so I'll probably need to write something myself

When I run it, cephfs-top consumes quite a bit of the CPU and
generates quite a bit of network traffic, but it doesn't actually
display the data.
I poked around in the source code and it seems like it might be
curses issue, but I am not sure.
Does there any data from `ceph fs perf stats` ?
Before I hit the same issue it was caused by the curses and windows
issue, we have fixed that long time ago, you can try to enlarge your
terminal size and try again.
If that still doesn't work please try to revert some recent commits
of the cephfs-top to see whether will it work for you. Recently there
have some new features supported.
