STEMWIN porting on ORIENT LCD

Hello, I am using STM32F769BIT6 processor along with 7inch orient LCD 800*480. i am trying to port STEMWIN lib on it. since the LCD is interfaced in RGB, i am using lin driver. 1. i used GUIDRV_LIN_16 & GUICC_M565, i can draw pixel by pixel in 200*480 active region for layer0. I am also using FMC based external 256Mb SDRAM for Frame buffer. the problem is when i am increasing the X axis more than 200, the drawn image is shaking and i am not able to make out what is drawn, pixels are scattered. 2...
