A discussion came up some time ago in the Linuxquestions Slackware forum: Xfce for Slackware Users
It seems there are a few who dislike the icon tool tip pop-ups in the Xfce panel. Back when, there was a settings that would toggle this functionality. In Xfce 4.16 there isn't...or is there?
If you enable desktop compositing (Settings -> Window Manager Tweaks -> Compositor), you can set the tool tip to transparent, effectively making it disappear. Simply edit the CSS in $HOME/.config/gtk-3.0/gtk.css to set the tool tip opacity to zero and restart Xfce.
