As you can see, the icons in the toolbar are not showing properly, but when I hover the mouse on the icon, it displays just fine. This is quite annoying and I was wondering if it is a sign that my system is compromised (hacked)
- is this normal
- how to fix it ?
Config : Lubuntu 18.04 LTS everything is default
