Okay, thanks for explaining. For now I am content with using “\omit
Staff.KeySignature” and “\revert Staff.KeySignature.stencil” respectively
to get rid of the problem.

What I found strange, though, was that in my score the problem only
appeared when there was a time signature change at the beginning of the
line. I couldn’t reproduce this in a minimal example.
