Menubar hides and reappears at startup of App Designer App.

Hi,

Whenever i try to start an app which has a menubar, the menubar dissappears for less than a second and then reapears.

Is there any way to fix this?

I created a Slow Motion Video to showcase my problem.

Code:

classdef app1 < matlab.apps.AppBase

    % Properties that correspond to app components
    properties (Access = public)
        UIFigure  matlab.ui.Figure
        Menu      matlab.ui.container.Menu
        Menu2     matlab.ui.container.Menu
        TabGroup  matlab.ui.container.TabGroup
        Tab2      matlab.ui.container.Tab
    end

    % Component initialization
    methods (Access = private)

        % Create UIFigure and components
        function createComponents(app)

            % Create UIFigure and hide until all components are created
            app.UIFigure = uifigure('Visible', 'off');
            app.UIFigure.Position = [100 100 640 480];
            app.UIFigure.Name = 'MATLAB App';

            % Create Menu
            app.Menu = uimenu(app.UIFigure);
            app.Menu.Text = 'Menu';

            % Create Menu2
            app.Menu2 = uimenu(app.UIFigure);
            app.Menu2.Text = 'Menu2';

            % Create TabGroup
            app.TabGroup = uitabgroup(app.UIFigure);
            app.TabGroup.Position = [1 1 640 480];

            % Create Tab2
            app.Tab2 = uitab(app.TabGroup);
            app.Tab2.Title = 'Tab2';

            % Show the figure after all components are created
            app.UIFigure.Visible = 'on';
        end
    end

    % App creation and deletion
    methods (Access = public)

        % Construct app
        function app = app1

            % Create UIFigure and components
            createComponents(app)

            % Register the app with App Designer
            registerApp(app, app.UIFigure)

            if nargout == 0
                clear app
            end
        end

        % Code that executes before app deletion
        function delete(app)

            % Delete UIFigure when app is deleted
            delete(app.UIFigure)
        end
    end
end

It's a bug. So... there are two ways to deal with it:

• Report the bug! :)
• Or... you can create your own graphic menu, controlling your tab object programmatically. For example... in the image below there is a tab object in the background.
