H2D flat surface corners on one side are rough

[Gerrit]

It just got mentioned in another thread, but there is a separate flow parameter for the top layers if you enable the developer settings.

Inconsitency of top layer with H2S

This is particularly a problem with the Bambu matte PLA. Slow down your top surface speed a bit. Enable the advanced settings (maybe developer mode in the application settings). You need to expose the option to set the flow ratio for the top layer specifically. I got better results with a top surface flow ratio of 1.05.
