Comments

Regarding the expected result, the glissando should be visible (maybe there isn't enough space being allocated, or it's being masked?). However, I'm not certain about its presentation - should the angle of the glissando not exceed the height of the grace note fret mark? What about the case of grace after?

(I forgot that it seems to only apply to tablature.)

I've just realised that it is visible sometimes, but I don't know why (attached score saved in nightly listed below):

Seems like extra room is allocated for the glissando unless it's the first note of the measure.

On a pitched stave, it is the opposite, somewhat (see attached score - produced in 1.3): Too much space is being allocated prior to the grace note - the culprit seems to be the glissando (if removed, the notes will move to the left - similar to the potential result below).

Potential result (approximate. Taken from 1.3):

Title Glissando between grace and normal notes in tablature too short at beginning of measure Wrong allocation of space if there is glissando between grace and normal notes

Updating the title to reflect the addition of the issue in #4 - it seems to only occur at the beginning of a system, rather than at the start of a bar.

#4 is expected; not great, but at the moment rather difficult to avoid.

It depends on the fact that the graces are positioned with respect to the chord they belong to and, if the chord is moved to allocate more space for the glissando (which happens primarily at system beginning) the grace(s) will move with it.

There is a symmetrical issue with after-graces, which are positioned as far right as possible: if a glissando is inserted between an after-grace and the following chord, any additional space for the glissando is 'eaten' by the grace, which simply move more to the right.

As glissando between grace notes is not *SO* frequent, I would imagine these are not going to be fixed any soon and would be probably better left to manual adjustments.

I'll check if the worse-looking layout in tabs can be improved or is exactly the same things as in std staves.

The basic idea is to mark it as "Postponed", if not even as "Won't fix it".

Still an issue. Open the attached score. The discrepancy between glissandos at the start of the standard staff and tablature is very apparent:
