If any Glyph is added to sComboBox other than the predefined arrows from the used skin then Button is always visible though sComboBox1.ButtonSkinSection := 'TRANSPARENT'; and the same way Rotation Of Arrows is not working though sSkinManager1.Options.RotateArrows := True;.
I have checked many skins, the problem is the same for all checked skins.
Please resolve the issue.
