  • Performance of measuring (and thus rendering) of RibbonTabItem (and it's contents) was improved by reducing the amount of measures required.
    Most of the time there should only be one or two measure calls when switching tabs, compared to six or eight in case of the showcase application.
    This is mostly achieved by getting rid of internal caching. The caching turned out to be more expensive than not caching at all.
