What you're effectively doing, IIUC, is providing an unsupported bit pattern for the Composite.  E.g., it's equivalent to:

	Composite c = new Composite(..., SWT.V_SCROLL | ...);

Composite doesn't support V_SCROLL, and the bits represented by V_SCROLL may actually be used/reserved for some other purpose.  So it's not entirely surprising that you're seeing unexpected results!

As Tom indicated earlier, you need to wrap your composite:

(It's too bad that SWT doesn't raise an SWTError on passing in unsupported bits.)
