I'm new on this forum and I'm writing because since I upgraded to Juno (via clean installation), I'm not able to see the multitasking-view application icon. Instead of the right icon I see the default one as you can see from the image.
How can I solve it?
Thanks to all

I've noticed that who encountered this problem is italian (including me) and thinking about it I've figured out how to solve the problem!
Editing the file (with sudo):
/usr/share/applications/gala-multitaskingview.desktopIcon[it]=vista-multitaskingIcon[it]=multitasking-viewHo notato che tutti noi che abbiamo riscontrato questo problema siamo italiani, e da lì mi è venuta l'illuminazione:
Andando infatti a modificare il file (con sudo):
/usr/share/applications/gala-multitaskingview.desktopIcon[it]=vista-multitaskingIcon[it]=multitasking-viewProbabilmente il file relativo all'icona italiana è mancante o chissà cos'altro.
You can solve the problem introducing the following line directly on the terminal:
sudo sed -i '/Icon[.*]/d' /usr/share/applications/gala-multitaskingview.desktop
It removes all entries with the pattern "Icon=[.*]" from the file /usr/share/applications/gala-multitaskingview.desktop that cause the problem and leaves only the correct line which says: Icon=multitasking-view
The icon is part of Gala and the problem has been reported on GitHub:
cat /usr/share/applications/gala-multitaskingview.desktopand copy it here (dont forget to paste it between ``` paste me here ``` )
