Are you using this via a Remote Desktop or a Virtual Machine?
As there are some known issues with flickering if you work this way.

But I'm not able to reproduce this problem on my system.

yes i use this system via Remote Desktop, i have tested direct and is ok.

I have clients with terminalserver or citrix heare i need a flicker free version ;-)

This is a known issue and this should be the solution based on the following thread:

You should set the TApplication.SingleBufferingInRemoteSessions property and set it to False.
