VisualUIAVerifyNative.exe finds a different BoundingRectangle than searching for several SWT Controls.

I have an SWT application with tabitems.

VisualUIAVerifyNative.exe highlights each TabItem correctly.

When I search for the tabitems using FindFirst method or Teststack.White I get a different bounding rectangle (the coordinates are wrong).

I am pretty sure both methods find the same TabItem. The same happens with HeaderItems.

If I do the same with Buttons, ComboBoxes both ways of getting the bounding rectangle show the same coordinates.

I am using Window 10.

What could I do to fix this problem?
