The image shows how it looks until a key is pressed or mouse is moved
When opening a file from Finder or Dock, Libreoffice does not show the document until a key is pressed or mouse is moved.
Libreoffice is started but the window list at the top only shows "LibreOffice File"
Pressing a key or moving the mouse immediately shows the file.
