We are painting the image on the control's parent, so it should also get clipped with the parent. I think this bug belongs to SWT,  but not sure. I'll leave it to Susan to decide that.

ControlDecoration painting outside

created in a Formpage with bare minimum:

Label l = new Label(form.getBody(), SWT.NULL);
l.setText("wow");
ControlDecoration nestedErrorDecoration = new ControlDecoration(l, SWT.TOP | SWT.LEFT);
final FieldDecoration fd2 = registry.getFieldDecoration(FieldDecorationRegistry.DEC_ERROR);
nestedErrorDecoration.setImage(fd2.getImage());

Forgot to mention, notice the 'ghost' decorator outside the FormPage on the left.  Not sure why it is rendered at all.  Once I resize the page however, it disappears.

Yes, seems to be the case. The simple test snippet is attached.
