It does not really work.
I started a new thread:
One of the errors in the logs is:
Number of blame output sections is higher than expected number of lines
EDIT: according to the other thread this is only a warning.
We hope this helps you. We can provide more details if needed.
Our git repo is very big and some files are very old (with probably a very long history per file).
We are back to version 10.6.0.82217
