Performing a screen capture using greenshot provides an image too dark to see hence the 'photo'.
Setting the opacity of a Fence to 0% results in the fence only being displayed on mouseover. Exactly as stated. Setting the opacity on a Folder portal results in a residual image of about 5-10% when using an OLED. On non-OLED screens, Folder portals behave like non-folder fences.
