Dears,
The result of the code below is different when skinparam is set to higher value to the state when skinparam is not set.
It seems the reason for the problem is, that PNG file is somewhere limited to 4096 Pixels.
So the result image for the 300 dpi is only a part.
@startuml
' Works
skinparam dpi 150
' Does not work from dpi > 200
skinparam dpi 300

The other code below does not work as well - the result image is cropped:
