When ties start on short notes, there is not enough space to display the tie properly. This causes ties to look like some sort of vertical line (or a v shape when zoomed in):

Perhaps an option can be implemented for the minimal distance between notes that are tied? This could be a style option that is controllable through options, with 0 being the current behavior. The units would be MEI vus for a minimum space between notes that need a tie between them. (Either from leftside to leftside of the noteheads or rightside to leftside of the notes).

The above example is using the default spacing options. When the score is stretched there is no problem:

But a full score may have one system that is compact and another stretched, so some ties will look ok, and others will be unreadable within the same score in the current state.

Longer example:

Screen Shot 2020-02-17 at 6 18 23 PM

Notice for single-note ties, there is an avoidance mechanism where the slur is moved above/below the notes to allow them to get wider. Perhaps this system can also be implemented for chords and/or use a minimal distance option as described in the previous message.
