Rendering issue AU in Logic

[leehu]

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.

Thx

BUG? Popup Menu Background and Logic Silicon

Logic Pro 10.6.0 and 10.6.1 on Big Sur silicon, JUCE on develop tip. The background of popup menus is showing a pink-ish background instead of being transparent: [Screenshot 2020-12-14 at 14.07.33] On other hosts on silicon (Live, Reaper, DP), and also on Logic Pro 10.5.1 on Mojave, the background is showing correctly: [Screenshot 2020-12-14 at 14.07.51] In drawPopupMenuBackground I’m using g.fillAll (Colours::transparentBlack);. Could this be just Logic’s fault?
