System.Drawing does not change it's behavior between "normal" and
double-buffering - so the problem is likely higher in the stack (moving to
MWF).

Having a Region with a NULL pointer generally (98%) means that it was freed or
garbage collection because no one kept a reference to the managed.

As for your second note (null Graphics) you should fill a separate bug report
with a stack trace.
