To reproduce: Add a RadRibbonBar, a tab and a group. In the group add a RadButtonElement. Add two buttons on the form. One for enabling and one for disabling the RadButtonElement. Start the application , collapse the RadRibbon and disable the button inside. Now expand it and you will see the visual bug. Workaround: Subscribe to the ExpandedChanged event of the RadRibbonBar and if the RadRibbonBar is expanded and the button is disabled re-enable and re-disable the button. This will correct its visual appearance.
