Description

When closing the Notes window (using close box or hitting Esc key) and later reopening it (by clicking the panel button), not only is the actual notes window reopened, but three extra windows (showing an empty greenish-brown background) appear that are completely useless.

After closing them, they will reappear after the next minimize/maximize cycle.

Environment: xfce4-notes 1.8.1 on Fedora 23, using XFCE as desktop environment.
