Does anyone know about this issue?

I tested and the GUI worked.

Take a look at the complete code (from creating a BaseImage to refreshing the screen)

Note that STM32103ZET6 only has 64K RAM and may run out of memory to cause instability.

Hi SSYYL： I am not testing on a microprocessor platform, I am testing GUI functions on a computer, so there will be no shortage of memory issues.
