The xfce4-panel tooltip doesn't show up when the cursor theme is too big.
I have tried https://www.gnome-look.org/p/1197198/ cursor theme with the max available size (48), and the tooltip is shows bottom of the panel, which is outside the viewport.
Reducing the cursor size fixes the issue.
All the devices running ArchLinux xfce4 (4.14.1) with different drivers and graphics cards are tried so far are affected.
