Why does the Delphi 2010 TRibbon control "flicker" on Windows XP, but not Vista/7?

Question

I've noticed that when I use TRibbon control that comes with Delphi 2010, it works flawlessly on my Windows 7 system. However, the application has some weird painting issues on a Windows XP system with the "classic theme" (I haven't tried the playschool theme).

I know there are other Ribbon components available from DevExpress and TMS Software, however purchasing a 3rd party control is not an option for this project.

Has anyone had this issue, or know of a solution?

Answer 1

Most likely this is a bug in the TRibbon code, the Microsoft ribbon renders perfect in both XP and Win7.

If you change your XP theme does the Minimise button shown in the image change to reflect your theme change? If this is the case the Ribbon code has probably been optimised for Vista and 7 and not been developed to run perfectly under XP.

You cant really resolve it unless you can modify the TRibbon code.
