The output display of renderer in HDMI is defective when DSI is enabled.
When the display image is still, it looks normal. When the display image moves, there will be flaws. There is a horizontal line, which divides the display image into two parts, one of which is like a delayed image frame.
I have been enabled DSI. This problem is also enabled by DSI, using two display interfaces
