set_vflip(True) not working in NICLA VISION


I tried the latest version (4.5.2) on NICLA VISION.
I was glad to find that I could use UART1 (PB9, PB8).

However, I could no longer flip the image upside down using set_vflip(True).
I had been able to do this up until now.

Thank you.

The latest is 4.5.5.
