Where is the "Network" coming from in the window list?

[c02y]

rofi -show widow will show all the opened windows, the problem is I noticed that every item in the list is started with the word "Network", I don't know where is the "Network" coming from, and apparently this word is wrong.

There is no "Network" from the source code of rofi, there is no "Network" keyword from the desktop files for applications such as mpv, emacs and Thunar.

FYI:
v1.6.1
empty ~/.config/rofi

That is what your window manager reports as the name for the desktop. You can change what it prints (see rofi -h or rofi manpage.)

Oh, sorry, I renamed my XFCE workspace as the name "Network", thanks.
