Ok I managed to find a workaround and got it working. What I did was
monkeypatch spark.components.gridClasses/GridColumnHeaderView and then
changed the code to

public static var dpiScaleFactor:Number =3D 1;

    public function containsMouseEvent(event:MouseEvent):Boolean

    {

        const eventStageX:Number =3D event.stageX;

        const eventStageY:Number =3D event.stageY;

        const origin:Point =3D localToGlobal(zeroPoint);


        origin.x +=3D horizontalScrollPosition;

        if (layoutDirection =3D=3D LayoutDirection.RTL)

            origin.x -=3D width;


        origin.y +=3D verticalScrollPosition;


        return (eventStageX >=3D origin.x) && (eventStageY >=3D origin.y) &=
&

            (eventStageX < (origin.x + (width*dpiScaleFactor))) &&
(eventStageY < (origin.y + height));

    }


and in my application on preinitialize I do

GridColumnHeaderView.dpiScaleFactor =3D (runtimeDPI/applicationDPI);


This is working fine for me on the device now and fixes the issue, but I'm
sure someone with a deeper knowledge of the SDK can take a look for a
better fix?
