To reproduce:
- add RadRibbonBar containing a Contextual tab group (composed of four tabs);
- add several RadRadioButton-s indicating which tab to be visible/collapsed:

private void radRadioButton1_ToggleStateChanged(object sender,
    Telerik.WinControls.UI.StateChangedEventArgs args)
{
    if (args.ToggleState == Telerik.WinControls.Enumerations.ToggleState.On)
    {
        this.ribbonTab1.Visibility = Telerik.WinControls.ElementVisibility.Visible;
    }
    else
    {
        this.ribbonTab1.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
    }
}

As a result, when some tab is collapsed, contextual tab group width is not changed.

======================
Workaround: set collapsed tab width to 0 and update ribbon captions's layout:

ribbonTab1.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
ribbonTab1.Size = new Size(0, this.ribbonTab1.Size.Height);

radRibbonBar1.RibbonBarElement.InvalidateMeasure(true);
radRibbonBar1.RibbonBarElement.UpdateLayout();
radRibbonBar1.RibbonBarElement.RibbonCaption.CaptionLayout.InvalidateMeasure(true);
radRibbonBar1.RibbonBarElement.RibbonCaption.CaptionLayout.UpdateLayout();

If the ribbon is collapsed and the user clicks a command tab to show the ribbon, and then uses Alt-Tab or another non-mouse method to switch to another application, the ribbon menu is 'stuck' and shows above all other windows. 
Switching back to the ribbon application and clicking will hide the ribbon. Using the mouse to click to another application does not have the same issue.

FIX. RadRibbonForm - theme is not applying correctly, when some changes are made to ribbon button while RadRibbonBar is collapsed.

Steps to reproduce:
1. Add button to some ribbon group.
2. Collapse the ribbon.
3. Disable this button.
4. Enable this button.
5. Expand the ribbon.

Workaround - subscribe to ExpandedStateChanged  event and reapply the theme. For example:

            this.radRibbonBar1.ExpandedStateChanged += new EventHandler(radRibbonBar1_ExpandedStateChanged);


        void radRibbonBar1_ExpandedStateChanged(object sender, EventArgs e)
        {
            this.radRibbonBar1.ElementTree.ApplyThemeToElementTree();
        }

You have a scenario where there is a maximized MDI child form in a RadRibbonForm. You try to close the maximized child form from the MDI box of RadRibbonBar, but instead of getting the form closed, you programmatically hide it, so that you can reuse it further. The moment you try to show that form again, it appears non-maximized which is not a correct behavior.

If you add a maximized child form with ControlBox = false or FormBorderStyle = None, the MDI control box of the RadRibbonBar in the MDIParent should not be visible.
