That video doesn't say that the bug is fixed, it says - as Larian said - that it should be fixed in a patch.
Larian's patch 2 notes mention that a bug for companions not talking when they should was implemented but doesn't mention Minthara specifically, like they did when they mentioned her problem.
I haven't seen anything new from her in game, either D.Urge or Tav (thank god I kept all my saves...XD) so I'm willing to say that I'm either expecting stuff that was fully cut and thus won't be there or it didn't fix Minthara and was a general improvement in the patch and not for her specifically.
While I'd love to recruit her on a good play through, I'd settle for actually knowing what's been cut and what's expected at this point. The evil path is generally pointless, so I might add that mod in that let's you recruit Minthara on a 'good' run and have a redemption D Urge playthrough instead^^
I'd refer you to this, it's a blessing! They've also made an alternate version that supposedly allows you to recruit her the more natural path while still being 'good.' I tested this one with the magic ring and it works, but I'm hesitant to see how much Larian's fix may affect or not affect her state.
