Cura strange infil slicing

[ShwarzBelij 0]

In video - simple model, wall width 1.2 mm, line width 0.4 mm, infill 100 %
Don't understand, why infill is not solid, and not simple line as inner and outer wall.

I went through a lot of settings - the issue is still there.

I did a little trick: reduced the line width to 0.39

But a lot of unnecessary movements of the nozzle (video)
What's bad - it increases print time

Set min wall flow to a non-zero value, try 50.

wall flow - does not help - the walls become thin, and the movement of the nozzle is irrational

Not wall flow, minimum wall flow!

minimum wall flow not helps
