It's certainly not a common word in German. In fact, this is the first time I've ever seen it, and all google search results are either dictionary entries or English articles that can be attributed to the Anglosphere's obsession with German compound words.

It is definitely colloquial and not a word you’d use everyday, but it is in Duden:

I love how I just automatically accept the German cookie banner without reading it (but understanding exactly what it says). Modern internet ist scheisse.

Might be regional, I certainly know it, I’m from southwest germany.

Northern germany also knows it. Maybe it has something to do with age. It's usage has declined over the years, I think. Maybe because it belittles the underlying issue, as it sounds rather "cute" to a native speaker. Just an educated guess, though.

Bavaria (southeast Germany) agrees. It's colloquial and - maybe regional - but not an uncommon word in my experience.

Hey, there is somebody wrong in the Internet!!!11

It's a relatively common word. I still remember that I first saw it as a kid in a Garfield comic strip ("Lieber Kummerspeck als gar nichts zu Essen").

focus.de: "Die Wahrheit über Kummerspeck - Wie die Seele uns dick macht"

spiegel.de: "Essen gegen Stress und Frust: Was tun gegen Kummerspeck"

bildderfrau.de: "Warum Kummerspeck so gefährlich ist"

I would not call it a common word. But every native speaker who reads more than Facebook status updates should have met it. Being an obvious compound of 2 words really everybody knows it does not require any real learning effort, the first time you see it you understand it intuitively.

A discussion about the passing of a great Jazz musician turns into a discussion about a German word about fat.

We didn't manage to divert the discussion towards the advantages of Lisp and Rust or the issues with current practices in job interviews.

The other week I similarly saw a conversation about calendar optimization to not look like Swiss cheese turn towards discussing the process of making Greek yogurt.
