I'm thinking the window might be redrawing itself right after your
own drawing and erasing it. You could try disabling the window's
auto displaying and flush the window buffer after your draw to
determine if this is the case.
I don't know where you're doing the drawing to know if it's safe
from being erased or not.

It's a local NSRect which I assume is interchangeable with CGRect
as they are the same.
I fill in the rect at the top of the method with the Rect of the
item in the window from IB and then I hide the item before drawing
to prevent my stuff from being drawn over.
CGContextFillRect doesn't do anything either. Just a blank space as
with PlotIconRefInContext.
If that were indeed the problem (some other drawing taking place after
his own and erasing it), an easier way to check for it would be to use
Quartz Debug, turn on "Autoflush drawing", set a breakpoint at the
CGContextFillRect call, and step over it to see if the rect is indeed
filled as expected.
