I have been experiencing some strange problems with ciompiz of lately.
Here's the problem :

I have enabled 'Desktop Cube' 'Rotate Cube' and '3D Windows'
---->When i have no applications open and i rotate Desktop Cube , i see strange flicker on the cube.The flicker appears as long as i rotate the cube

---->When i open an application window and then rotate the cube,the rotation works just fine without any flickers.

Anyone has the solution ?
I have ATI HD 4xxx series graphics card with OpenGL drivers.

And i have noticed that 3D Windows shows thick ugly borders for minimized applications on rotating the cube. i.e borders are displayed even if the application is minimized.
Please Help me with this.
