Normally when selecting a file (in the "Log / History" tab, when an unstaged file is selected) the right pane shows hunks of changes. Sometimes this pane is completely empty. I have to select another file and then back to the original one to see any changes. As if it doesn't update itself for some reason, or something.

This is especially annoying when there's only one unstaged file and no staged files. I have to select a different commit (and then back) to make it display hunks of changes

This bug is not reproducible by request. I can't make it happen, I just happen to notice this problem form time to time.
