Bobs being drawn off the sides of the AOZ screen
Bobs are randomly being drawn at the side of the AOZ screen in the browser window (see picture)
If the window is re-sized, they disappear.
I've attached an updated version of Text Effects that I used to produce the photo. If you run that, and use the Preset '0', resize the window height and you should see bobs flickering at the sizes of the AOZ screen. Other than that, I cannot reproduce the bug on demand.
