Graphics.Clear() in Terminal Services

There's a known issue with Graphics.Clear() causing a generic GDI exception
in Terminal Services. For more info:

and

We are periodically seeing this issue in our own software and I have removed
all the Graphics.Clear() calls, but in delving through the framework, there
are a number of places where it's called. For example,
ImageList.Images.Add() eventually results in a Graphics.Clear() call.

The problem is I can't reliably reproduce the issue and what I'd like to do
is find out if anyone out there knows how to reliably reproduce the problem.

ImageLists are used directly, and indirectly (via S.W.F controls) and I
basically need to establish whether or not this problem is fixable by us. By
that, I mean, currently, the exception has shown up only when we directly
call Graphics.Clear(). But if there are situations where it's going to
happen when adding images to an ImageList, there's no point in us fixing all
the possible places in our code where Graphics.Clear() is called directly or
indirectly.

Anyone have any ideas on this one?
