环境： 野火 霸天虎V2，4.3吋触摸屏(lcd/ILI9806G, touch/GT911), ucos3, lvgl9,

显示+触摸无问题，但全屏刷帧率不行。

无法开启 例子3，听说是sram不够。

#if 0
    /* Example 3
     * Two buffers screen sized buffer for double buffering.
     * Both LV_DISPLAY_RENDER_MODE_DIRECT and LV_DISPLAY_RENDER_MODE_FULL works, see their comments*/
    static lv_color_t buf_3_1[MY_DISP_HOR_RES * MY_DISP_VER_RES];
    static lv_color_t buf_3_2[MY_DISP_HOR_RES * MY_DISP_VER_RES];
    lv_display_set_buffers(disp, buf_3_1, buf_3_2, sizeof(buf_3_1), LV_DISPLAY_RENDER_MODE_DIRECT);
#endif

有好的办法解决 帧率的问题吗？
