Hello all,

This is my API to draw a button.
As per the picture on the attachement , the button is rendered as expected but the background is not correct !!
In this example I cleared the screen to red, and then sent the CMD_BUTTON, so any idea about whats behind the button ??
int16_t bt81x_draw_button (uint16_t u16_Xpos,
                           uint16_t u16_Ypos,
