Rendering issue AU in Logic

Hi, have a strange rendering issue for popups.

I have this code to render rounded corners on popups:

    g.setColour( findColour( PopupMenu::backgroundColourId ) );
    g.fillRoundedRectangle( 0, 0, width, height, 4 );

    g.setColour( findColour( PopupMenu::textColourId ).withAlpha( 0.6f ) );
    g.drawRoundedRectangle( 0, 0, width, height, 10, 1 );

which generally works fine. However, in Logic there are little pink spots where the rounded corners are.

In other DAWs these appear an non-opaque, so figure this is a Logic rendering issue, but just wondered if anyone had any suggestions. The same AU renders fine in Live.
