Bug description

There are clicks at the frame boundary e.g. at 1:44 - 1:46.

The issue is not reproducible with a later version of main. However, it could be that it is because a different mode is chosen and the issue is no longer triggered. It would be good to verify that the artifact is not present when the mode selection is the same.
