Hi, first or all, thank you for making this amazing repo.
I really like the plotting feature that allows me to understand what is happening.
I have three issues/questions, and I would really appreciate if you could solve these, especially the first one.
1. Plotting unionfind decoder
I'm running the following in jupyter notebook.
%matplotlib qt
from qsurface.main import initialize, run
code, decoder = initialize((5,5), "toric", "unionfind", enabled_errors=["pauli"], plotting=True, initial_states=(0,0))
run(code, decoder, error_rates = {"p_bitflip": 0.05, "p_phaseflip": 0.05}, decode_initial=False)
For the first three plots (initialization, error applied, ancilla qubits measured, everything is fine.
But when I hit next, another window pops up, and the grid doesn't show anymore.
It looks like this:

Could you please solve this, so that the grid shows up, just like when I use the mwpm decoder?

- Question: What is info / bitflip / phaseflip in this image?

Again, I really appreciate this repo, and I hope you reply!
