This is /your/ dialog I take it. Difficult to debug without the code!
Do the DialogDraw demo, the align dialog, and the galleries work
on your copy? DialogDraw and the align dialog use GRenderRegion,
and the galleries use OSRenderRegion to draw the wxCamDrawControl.
With such extensive use I doubt it is /fundamentally/ broken. I
could well have broken something though I suppose.

That normally indicates you have tried to double destroy the dialog.
When you say "if I close the dialog" what are you doing to close it?
Hitting the close button? The correct course of events should be
that the close button gets intercepted, and sends a DIM_CANCEL
(through dlgmgr), which in turn causes your dialog do do End().
This should cause the DialogOp do be deleted, and its destructor
calls DialogManager::Close and DialogManager::Delete. It sounds
to me as if that isn't happening.

Does the problem go away if you (temporarily) remove the wxCamArtControl
from the XRC, or is this an unrelated problem?
