Diffusion Display abnormal

What is the cause of the abnormality of Diffusion?

What’s the abnormality in the picture?

I was able to display the contents of the file before I upgraded it,I’m not sure if this version just doesn’t display or something is wrong

Which version of git is installed on the server?

If it’s old (before 2.11), upgrading it might solve the problem.

This might be related to This path was a submodule for all directories, never used submodules

After I upgraded the Git version from 1.8.3 to 2.7.2, the problem was solved, it was the Git version, thank you
