Tiny flakes in my beer?

[QuercusMax]

I'm getting close to the bottom of a keg of Honey Tangerine Golden Strong and in the last 2 half-pints I have poured tonight I have noticed tiny little translucent white flakes. They don't seem to affect the taste or mouthfeel.

Anybody else seem something like this? Is my beer ruined? Its brilliantly clear aside from these flakes.

(I'm not actually concerned, just curious.) This was brewed in March, and has been in my keezer since May.

Sounds like protein flakes. Happens to the very best commercial breweries for no apparent reason. Anecdotally, I've noticed it seems to be common in beers heavily hopped with English varieties. Here's a Schlafly Export IPA from 2013 (thanks to MikeSTL for photo):
