With Artful 17.10 Wayland, any app of LibreOffice opens with a small window. Previously, it opened with a "common size" or the size you used previously (see attachment)
If it was opened with a full screen window the previous time, it opens in full-screen mode. If you check the "windows size" button, you may get a more smaller window with only the menu of LibreOffice.
