Description of problem:
Issue occurs during Evolution startup.  The application window is visible but only briefly, maybe 1 second or so; not long enough for user interaction.

I have been alternating between Wayland and X11 sessions, so I can help test Wayland as described here:
https://fedoramagazine.org/help-fedora-test-wayland/

Currently, I have observed this issue only in Wayland sessions; however, it does not happen consistently.

Version-Release number of selected component:
evolution-3.18.1-1.fc23
