PxMatrix P5 RGB 32x64 320x160mm not correct display

Rules

Post your code
Post a picture of the problem and describe what you expect to see
Run the pattern test and post the result as gif/video (need to have a bit more than one full RED/YELLOW/WHITE cycle)
State what version of PxMatrix you are running and what MicroController you use
I use example cone pixeltime

I was try different settings scan rate n pattern.. Its still doesn't not display correctly I use esp32, P5 32x64 RGB panel

Test pattern Display. Begin(16) https://youtu.be/h0oy6MdZapE

I have the same board as you

test pattern was OK PxMATRIX display(64, 32, P_LAT, P_OE, P_A, P_B, P_C, P_D); display.begin(4); and display.begin(8); but with 16 its start with green line at bottom IMG_20200429_193600
