TRibbon Rebuilds TRibbonGroups randomly

Question

I'm noticing that with my application the TRibbon is flickering and rebuilding itself at seemingly random (but reproducible) times. By random, I mean I don't see the connection.

• Windows 7 x64
• Delphi, RAD Studio XE2, Update 4
• Rubbon on main form, multiple tabs (shouldn't matter)
• 3 TRibbonGroups on the tab I'm reproducing the issue on: First just has 4 normal buttons in it. Second has 2 buttons, a splitter, then 6 more buttons. Last one has just 3 buttons.
• Add a button with this action:

procedure TParentForm.Button1Click(Sender: TObject);
begin
  Screen.HintFont:=Font;
end;

Any advice on a workaround would be greatly appreciated.
