In the Calendar Month View of the Evolution user interface, Appointments are drawn within the day blocks. They begin with the time and the beginning of the Appointment Summary. When the mouse is moved on top of the Appointment rectangle, a content window is drawn to show additional details. However, the context window display amounts to a flicker as it almost immediately disappears again.

This issue seems to be limited to a GNOME/Wayland session. The content window persists as expected in a GNOME/Xorg session.
