I looked through the library code and the core functions used and I see nothing wrong
I have no idea what is going on but if you can attach your logic analyzer and see if there is data coming out and if it's the same

I checked the datasheet and it looks like it can handle 10MHz SPI and the shiftOut method provides 500KHz, so it should be well in specs even if something somehow messes the timing at some point

I am no longer convinced that this is a project problem. I re-implemented in WiringPi and have same issues. I looked at low level traces using a logic analyzer and all looks good. Am awaiting delivery of a different 7 segment module to test differently.
