I haven't encountered the issue in regular windows (at least not that I can recall).
I have encountered something similair when using selectrums new group-title-format.
where there's a $ shown on the right hand fringe because the input is too long but
that may be unrelated.

```lisp
(selectrum-mode +1)
(completing-read "foo: "
                 (cl-loop for i from 1 to 10
                          collect (concat
                                    #("    " 0 4 (face (:strike-through t)))
                                    #(" hello ")
                                    #(" " 0 1 (face (:strike-through t) display (space :align-to right))))))
```

I believe selectrum renders completion candidates onto a virtual buffer so maybe this
is an example of what you described.
