I never see posts about this, I feel like it’s just me :).
Freetube AUR update a couple days ago left me this, in Plank:
some big neandrathal Freetube icon when opening normal icon.
I did my tried-and-true method as this happens to me on occassion with a few apps after update:$ sudo gedit /usr/share/applications/freetube.desktop
go to NAME. Make it all lower-case.
congrats, it disappeared.
