How to reproduce

1. open XYZ.3mf project
2. Set Sparse Infill Speed to 20 and slice
3. Set Sparse infill speed to 30 and slice

Observe dramatic difference in sliced wall speed on the color map

Actual results

• Sparse infill is set to 20mm:
  
  The outer wall speed is 200mm/s according to the colormap

• Sparse infill set to 30 mm/s:
  
  The outer wall speed is about 70mm/s, except a layer that has a bridge!

Expected results

Wall speed should not be influenced by infill speed settings.

This should be related to the min layer time.

There are issue closed by timeout #4191 which points to the non-obviousness of that setting.

There another PR #5148 which addresses the same issue.

Correct answer.
I tentatively suspected something like this, but it didn't occur to me (never printed that fast before).

Layer time can be seen here:

The setting is in filament options:

The settings is perfectly justified and below there are options to control its behavior.
