Evidently OpenGL doesn’t guarantee drawing the FBOs in the same order they were painted in.  So I fixed this by putting an AdvanceDepth() call between drawing background objects (ie: those with a bodybackground fill) and foreground ones.

I’ve also turned caching back on.

Cheers,
Jeff.

However, when I scroll {0,0} off the visible area, the background fills are drawn *after* the text.  (I put one text half in and half out, and the text *is* still getting drawn, it’s just under the background fill.)
