I had the same thing happen to me on a brand new out of the box 550 MK2. almost finished with the porting and then the plating started to flake off. once i started picking at it, it just kept coming off. I still have the cylinder on the shelf.

With a cylinder like mortalitool described, I have to wonder.
If it had been just installed as, a stock out of box cyl, with no mods.
Would it have developed an appreciable hot spot where the plating was loose?
Think for a moment. The lack of a bond also means lack of proper contact to transfer heat.
I feel sure NASA would see the difference if it were a rocket part, but what about the demands of a saw cylinder under running conditions?
How would you do a non-destructive test for the non-adhered plating?
Ultrasonic or X-ray?
Or for on my budget... Take a 90 degree pick and tap everywhere while listening for changes in the sound?

Wrong.....

The plating is loose pretty much everywhere.

Anyone seen this in an OEM jug before.

It's a Mahle cylinder.

Yeah, the Chinese knockoffs are better than that...Usually OEM stuff has good quality control..

I vaguely remember a guy on one of the forums somewhere who bought new saws to strip for parts, selling on ebay etc.
He was finding so many irregularities and faults with cylinder liner/piston castings that he eventually ended up selling the crankcase with the cylinder and piston attached as a complete unit.
From personal experience on a number of saws, I've come across issues, in particular the old Stihl 020t's which had pock mark faults in the cylinder liners

The not so funny thing is if it seized it would be diagnosed as straight gassed claim denied.

Electrolux to Mahle: We want cheaper prices on the cylinders You are making for us!

Mahle to Electrolux: Sure!

Mahle to their production department: Reduce surface treatment time and completely cut quality checks on all Husqvarna/Electrolux products!

Electrolux CEO: That'll get me millions in bonuses this year.

Husqvarna customers: WTF!!!

That is exactly how it works from what I understand. Maybe not in this particular situation, but in general.

Whew...
Grateful for PQC
Primate Quality Control

Unfortunately is a lot more expensive doing quality control way down the line.
Unfortunate indeed.

That's another good reason for me to not buy a new saw. I usually buy older ones and fix what's wrong with them...
