Customized main screen Windspeed/dir dials need to remove glass effect

Using the May 24, 2024 download on Win 11 23h2 pro all of screen is in dark mode theme so trying to get my WD main window to comply with that. Changed background colors of wind speed and wind dir dials to black with white numerals - looks good except for the little “glass effects” over each dial – a long time back I seem to recal there was as setting to turn those on or off but I’ll be switched if I can find anywhere that is now. Anyone have an answer? PLEASE
