please verify the code below.
initStaticBackgroud() function is being called once at the beginning of set up.
And tft_display function is being called every 1 sec continuously. Image shape is being loaded with black solid color. If I try to load that image from flash using EVE Image Editor tool, then I am able to load with colors. so I confirmed that image stored in flash has correct details and not corrupted. it's just when I try to load using ESP32 with below code, is when I am getting issue. something I am not following correctly I think.
