Sorry I did not successfully post my question last time.

What I want is to fix the screen rotate problem. I am running the stm32 cube demo code (STemwin example) on the STM32F429 eval board which is connected to a 800x600 LCD. The screen runs well if in the landscape, but when I tried to rotate the screen 90 degree, the back ground is looks like out of sync (text is still ok). I do some search online and someones said it is caused by the no enough memory. I tried to use the external memory for GUI as

#define GUI_NUMBYTES (1024) * 510

but does not work, even I switched back to the origianl 480x272 LCD, the portrait display has the same problem. Please see the attached screen shoot.

Anyone has the idea how to fix it?
