I have a problem in a computer, with the last mint update , miont notfication area don't have icon.
If i choose Mint-X : then it's completely transparent, if i choose cnome/gnome-wize it's black (for icon).
I test with different Mate theme (Mint-Z/Mint-X/ClearLooks ....) but never have something good.
Sometimes i have the icon (lot of manipulation : change them/remove-add notification area) but when i restars : it's allways transparent or black.
I resinstall mintupdate mintupdate-icon, mate-applets via synaptics.
If someone have another idea
