gitg displays diff twice

[vsespb]

gitg displays diff in diff window twice, sometimes.

steps to reproduce in my case:

1. stage a file
2. cursor will jump to next unstaged file (that file should be "new")
3. content of file displayed twice in diff window
4. Ctrl-R will fix view

I saw once when duplicate diff was for "modified" (i.e. not new files), for multiple files, and Ctrl-R was not fixing it sometimes. But this is not reproducible.

Attaching screenshot. You can see diff for .sh file. Content is duplicated (you see two shebangs with /bin/sh).
