Version 4.4 - Issue with playback of distorted guitars

Some context: I usually enter the notes in a guitar chord in different voices, as I often write polyphonically. For example, for a C major chord, I'd put C in voice 1, E in voice 2, and so on.

After updating to version 4.4, it seems the playback system no longer recognizes these notes as being played on the same guitar. This is especially noticeable when using distorted (heavy) guitars, where chords notated this way now sound like several single notes played simultaneously, instead of having that "crunch" that distorted guitar chords should. Can someone look into this? Thanks!
