I always see annotations from the current line in the Debug Console. Is that expected? I find it distracting.

This is definitely not expected or by design. I have seen this a couple of times, but never seem to be able to reproduce it. Do you have any steps?
I see it often when debugging, but not always. I don't know what makes it show up but I'll pay closer attention and try to figure it out.
I believe this will be fixed in GitLens 7, please re-open if it reoccurs.
