Is this frothy texture normal?

I noticed this frothy/foamy texture in this lassi and wanted to get your opinion. Is this normal, or could it indicate that something is wrong with it?

Finally got it

But when I taste it it feels like there is some powder which is not mixed completely , it is like plant protein or yeast protein where after taking it some powder feels in the mouth
