You need to adjust the opacity of popup windows.
The following instructions are applicable to Xfce 4.8 and newer.
Open Settings Manager or run
xfce4-settings-managerGo to Window Manager Tweaks - Compositor
Look for the option Opacity of popup windows: (toward last entry)
Drag the slider control until the furthest right (toward Opaque)
Finally, click Close
Now the popup menu is no longer transparent and fully opaque.
Before: Semi-transparent
After: Fully opaque


alt+scrollover a window decoration (top bar) allows to manage the window transparency.
