haven't noticed this mentioned in the change logs so I'm bumping this.  Does this not happen for other people?  

I don't see this happen with every shortspear/shield pose, so as a temporary workaround, the devs may just want to change the default pose for Kraxis units that are affected by this so it's less likely people will notice it right off the bat.  Then it can be fixed later since time is short now.

It does and there are few other graphical glitches like Procipinee dress shows through her cloak from time to time and some other things that I don't know if there is a good fix for all these graphical problems. I do agree that at least the portraits should be fixed at the very least.
