Shifted colors and shifted lower half with multiple panels

Hi,
I have three panels that show shifted colors all over, and a shifted lower half when daisy-chained together. A single panel seems to work fine. Adding a second induces a 1 pixel shift. Adding a third adds another pixel shift.
Here is an example:
The test patterns work fine. I've uploaded a video of the test pattern, followed by the mario test image here https://www.youtube.com/watch?v=I0p8bEszOuA
I use an ESP32 with 1/8th and already unsuccessfully played around with mux and scan patterns. Setting a mux delay didn't change anything. I've tried the release version and the master version of PxMatrix.
The panels are P6-8S with 32x16 pixels. The chips on it are: TC5020A, SM74HC123D, SM74HC245D. It only lists A,B and C on the connector.

Hi!
I just registered to github just to reply here...
I was having the same problem and then it struck me... what I was seeing was the data buffers "loosing" one clock cycle. Or better, clocking one data cycle late on every new row, which only happens after going through the longer side of the cable.
I slowed the SPI bus clock speed and that solved the issue. To do that, you have to define the following variable:
#define PxMATRIX_SPI_FREQUENCY 10000000
BEFORE calling
#include <PxMatrix.h>
The original value for it was 20000000, and I slowed it to half. I believe not such a drastic reduction is needed but this is good for me!
Also, please take care in the examples it is incorect spelled, so please, double check!
A last note, the issue is not with the led drivers, Chipone ICN2037pb in my case, but with the buffers, SM74HC245 in my case.
