Hi, I had the same problem with H745ZI-Q, and I figured out, that it's problem caused by "pgm_read_xxxx()" macros. I changed for example: "uint8_t *bitmap = (uint8_t *)pgm_read_pointer(&gfxFont->bitmap);" to "uint8_t *bitmap = (uint8_t *)gfxFont->bitmap;". i did it only in functions "write" and "drawChar" in tft.c. Now it works well for me.
You mean like a screenshot. Well i don't know for sure but you can weite the data simultaneously on screen and sd card. Otherwise if you have a controller with enough memory to store the entire frame buffer, you can just copy that frame buffer to a file in sd card.
