I think soft wrap is causing this. If I enable/disable soft wrap in the settings I get this issue.

Just received this issue after closing a diff, doing some other work in the other panel, and then returning to the panel I had diffed originally. Closing time machine changed nothing, and I continued to get this error every time I tried to click elsewhere in the document. Closing the tab and reopening the file resolved the issue.

Any update on this?

The only workaround that I found is...

When you want to close the split-diff pane, close the time-machine pane first. If then, you can avoid this annoying bug
