You're right that surface_leave is the counterpart. The warning is there to tell you it didn't get called, which usually indicates a compositor bug. It warns when the compositor sends two events about a surface enterering the same screen without sending a leave event after the first one.
We just ignore the second event, so probably nothing bad will happen, but we print that warning in the hope that it will lead to compositor bugs being fixed.
I wrote a patch to clarify the meaning a bit: https://codereview.qt-project.org/#/c/247560
Which compositor are you running?

To whom it may concern:
We have seen the following error when one window is closed and then re-opened with wayland-egl since QT5.9.
However, everything seems to work well except the warnings.
Unexpected wl_surface.enter received for output with id: 10 screen name: "DELL P2417H" screen model: ""
Do we need to worry about this warning from void QWaylandWindow::surface_enter(wl_output *output)?
I added a trace at QWaylandWindow::surface_leave(wl_output *output), but it I s never hit.
Which function is the counterpart of surface_enter?
