When using the Background System Box and the Layer Object, if one moves a layer with a Background System Box in it, the image in the Box disappears (this possibly only happens when scrolling the layer out of the visible frame and back again). Also, sometimes the Background System Box refuses to scroll at all.

I have a neat graphical effect with my App's menu bar, that whenever anything changes on it, it scrolls out of the screen and back with new menu bar content. I would like to change the background of the menu bar, and to do so I added the Background System Box to act as an "Active Quick Backdrop" object, with a second Box behind it with a different image.

Note: This glitch seems to happen whenever you move the Background System Box, regardless of whether you are moving the layer or not.
