Description Martin Koller 2017-03-21 12:12:54 UTC

I use a desktop file to start libreoffice with a document to open.
The desktop file is used from a quicklauncher in a bottom panel.

What I often see since 16.12 (had no issue in 16.08) is the spinning animation in the taskbar when I start loffice, which keeps spinning although
- loffice is already up and running
- I explicitely have StartupNotify=false in the desktop file (why do I see the spinning at all?)

Here is the .desktop file:

Add a StartupWMClass to your .desktop file that matches the WM_CLASS of the eventual LibreOffice window.

(Note that this will probably work better with 5.10 / git, as we recently rewrote StartupWMClass handling somewhat.)
