Blinking lines on the display of STM32U5G9J-DK2

[seijimura]

Please tell me about the display issue. There are lines on the display, and they appear to be flickering.

This issue occurred when I connected to the Raspberry Pi via GPIO and pulled out without turning off the power of the STM.

I have tried pushing the RESET B1 button, unplugging and replugging the power, and writing a new file, but cannot solve the problem.

If there is a way to reset the display or something,could you tell me?

↓ There is a vertical blinking line.

↓ After writing a black image file, the afterimage of the previous file is still there.
