It's not a problem to free lv_image as the data is copied to the img1 (or img2 or img3) object in the lv_image_create() function. But I think the problem is much deeper than that, maybe a DMA problem or something... The display works well with a clock lower than 22MHz, but as soon as I want to go hi...

No it's not a problem, the data is copied into the img1 (or 2 or 3) object with the lv_image_set_src() function.

But I think the problem is much deeper, maybe related to DMA or something like that, I don't know.

Someone should be able to reproduce my bug, do you work for Espressif @MicroController ?

You're right, it's lv_display_set_buffers(display, buf1, buf2, 480* 272* sizeof(lv_color_t), LV_DISPLAY_RENDER_MODE_FULL); copy and paste error when I wrote my post for the forum. Yeah sure : void screen_display_image(void) { FILE *f; f = fopen("/spiffs/ICON_DEVICE_VBC8_PENDENT_COLOR", "r"); if (!f)...
