I made a test stl in Fusion 360. It is a 20 mm cylinder, exported in high resolution (as I always do). But now I can not print it faster than 50mm/s. Before the upgrade I never had problems at 100mm/s.
The reason for the upgrade was the linear advance function. I often have issues with too much material in the edges, so I wanted to test this interesting function. But yet it is disabled (LIN_ADVANCE_K = 0).

I got curious and did the same and saved it in high and medium resolution. The high-res. cylinder has ~1600 facets, the medium-res ~600.
Marlin on 8bit MPUs seems to be at the edge with all these new features they try to implement ( to keep up with 32bit controllers? )
IMHO you have three options:
Downgrade to the old Marlin
Use medium or even low res. .stl parts
Get a 32bit controller
I always use medium res .stls, never had issues with details.

How comes it starts bad then comes up OK ? Is the "engine" warming up and able to cope with the "load" ?
I guess, he manually reduced print speed until the buffer-underrun stutters ended...
