The issue you're experiencing (expected vs actual, screenshot, stack trace etc)

In the demo, I added the following to org.pushingpixels.radiance.demo.component.ribbon.BasicCheckRibbon.configureTaskBar():

    ribbon.addTaskbarCommand(Command.builder()
  	      .setIconFactory(Edit_clear.factory())
  	      .setAction(commandActionEvent -> ribbon.setMinimized(!ribbon.isMinimized()))
  	      .build().project());

In general, it works as expected. However, every now and then the ribbon tasks all become blank:

The definite cause is not clear but it happens after some combination of repeatedly minimizing/restoring the ribbon and repeatedly clicking the various ribbon tab toggle buttons. It can sometimes take a while to get the issue to occur. When it does occur, the only way I've found to restore the ribbon tasks is to change the skin.

Not able to reproduce this so far on macOS. Will try on a Windows box.

Reproducible 100% on Windows but not on macOS:

• Run the modified demo with the taskbar command wired to minimize / maximize the ribbon
• Click that taskbar button to minimize the ribbon
• Single click on the "Write" task to display it in a popup
• Click that taskbar button to maximize the ribbon

End result is that the ribbon is maximized, but does not show any task content
