Git History diff not showing

I’m working on a GIT project, the GIT integration works fine (commit, push, …) but when I right-click on a file and select “history”, the left part of the screen shows the git log however the right part which is supposed to show a diff is always empty.

And the two buttons “Diff of Changes” and “Diff ith local copy” don’t have any effect either.

I have the exact same issue. This is a definite deal breaker for me to actually purchase this IDE.
