Of course what I’ve noticed is merely an editing error, but from a different perspective it looks quite unusual.
Take a closer look. You can see some parts of the Sugarcube Corner building through Cozy Glow. So, Cozy Glow is partially transparent. And it appears that only her head is transparent. This can be interpreted as the fact, that Cozy Glow is actually a desperately disguised ghost. Trying to disguise the ghost of a cartoon animal to look like a living animal is actually possible, albeit highly complicated. This process requires a large amount of hair dye, and in some cases, contact lenses.
In this case it appears that either the hair dye is already peeling off, or it wasn’t applied properly on Cozy’s head.
This leads to a rather dark theory that Cozy Glow actually died due to petrification and her ghost was picked up by Daring Do. She tried to disguise Cozy’s now-supernatural look by covering her with several layers of hair dye, and now tries to guide her towards redemption.
Oh, and yes. This version of older Rainbow Dash is way better than what we’ve seen in The Last Problem.

If your wondering why cozy glow with Daring Do well here’s the why -
 
Daring do and ahuizotl ended up adopting cozy glow as there own child, ponies didn’t forgive Cozy glow for what she has Done, but Daring do and ahuizotl do forgive her. Cozy might do some bad things here and there but cozy apologized for her actions and daring do and ahuizotl and there rest of there other kids enjoy having a new sibling in the family ;3
 
and Cozy did something bad, yeah she in big trouble xD
 
Hope u like it!!

Tear her limb from limb!

They will draw and quarter her, except with halves instead of quarters.

Looks like Daring will have to put a certain filly over her knee…
