You need to adjust the opacity of popup windows.

The following instructions are applicable to Xfce 4.8 and newer.

  1. Open Settings Manager or run xfce4-settings-manager

  2. Go to Window Manager Tweaks - Compositor

  3. Look for the option Opacity of popup windows: (toward last entry)

  4. Drag the slider control until the furthest right (toward Opaque)

  5. Finally, click Close

Now the popup menu is no longer transparent and fully opaque.

Before: Semi-transparent

Xfce4 menu is semi-transparent

After: Fully opaque

Xfce4 menu is fully opaque
