Indeed, on-screen.el adds itself *globally* to `after-change-functions`
so it's also applied to temp buffers.  Sounds like a performance bug in
`on-screen.el`.

Do you still see the performance problem if you don't enable `on-screen`?

Not necessarily: it could be too slow (because of the cost to
enter/leave `combine-change-calls`).
