Could it have been the filament? It would seem so. Maybe the filament has some moisture in if from the factory (some steam bubbles pushing it up?). That's something I have seen but maybe something else changed like the humidity, when the air conditioning turned on and blew across the room, or maybe I printed PETG and then went right to PLA without cleaning the bed...dunno.
Fortunately it's livable as far as the print goes, and it will likely go away by itself...until the next time.
I thought perhaps it was the filament, but its happened now in several rolls and two different brands. I get it on most prints i do unfortunately.
Its almost like a reaction between the filament and the PEI bed but i dont know why. Its funny though that when a line starts to lift the rest follow on like a wave which gives that weird ripple affect.
It just annoys me when i cant figure something out.
Any other ideas or anyone else getting the same problem?
