The change about tie spacing in MuseScore3 from in MuseScore2 is wrong.
The tie between each single note generates unnecessary space in MS3. You can find the tie is longer than the minimum tie length. MS2 doesn't generate such space in this case.

I think MuseScore should expand gaps only in the case the ties connect from chords to chords. MuseScore should achieve "Better Placement" in this picture.

Title Tie and Spacing. The wrong change of MS3 from MS2 ⇒ Too much space allocated for minTieDistance when tie overlaps noteheads
Priority ⇒ P1 - High

Updated title to reflect what is actually happening. We add minTieDistance to the space between tied notes, but in many cases the tie will overlap the notehead so we don't need to allocate the full distance between the notes.

In 2.x I had implemented a fairly complex two-pass scheme to handle this, calculating the space during the first pass based on a whole bunch of factors then allocating it later. Ideally we could borrow that code (which is actually still present but has no effect), but at the very least we could at least optimize the single note case, which is the main problem here.

Turns out my original code to add space more intelligently was already reinstated, only a week after the current code to make room for ties was introduced! Left hand not knowing what the right was doing :-). Anyhow, we can now safely remove the new code, which is what is responsible for the extra space. Here is a PR to accomplish that:
