CLUT8 Usage and LCD toggling for reduce RAM

HI,

I was using RGB565 earlier for displaying data and my RAM consumption was 580KB for 480x272 display. I want to limit my Graphics RAM to 300KB to 400KB Max, so i started using CLUT8,8bpp. I am using event as well. But i am getting window flashing for each update of timer of 1 second.

This issue was not happening in RGB565, 16 bpp. How to rectify this issue in CLUT8? Attached my program.
