QPrinter bug?

[lni]

Hi,

I have a brush with custom QBitmap, as shown. Inverted scale was applied to the QBrush to remove scaling effect on the QBitmap.

QTransform xf = painter->transform();
 
  QTransform brushXF;
  brushXF.scale( 1 / xf.m11(), 1 / xf.m22() );
 
  QBrush bs = brush();
  bs.setTransform( brushXF );
 
  painter->setBrush( bs );

QTransform xf = painter->transform();

  QTransform brushXF;
  brushXF.scale( 1 / xf.m11(), 1 / xf.m22() );

  QBrush bs = brush();
  bs.setTransform( brushXF );

  painter->setBrush( bs );

In screen, the graphics look fine, but when do QPrinter, the inverted scaling on QBrush was lost, see attachment. Do I do something wrong?
