This is equivalent to using HW tooltip every time on the HiDPI screen, and unfortunately it has a side effect.

If the tooltip is HW it is drawn in a separate window and is not inherit opacity/translucency of the parent,
you can check that by these changes in the test:
     frame.setLocationRelativeTo(null);
    +frame.setUndecorated(true);
    +frame.setOpacity(.5f);
     frame.setVisible(true);

I still think that using right GC in the tip, is probably better way to fix it.
