How to reproduce

Create new project.
Insert standard cube.
We will evaluate the upper surface.
Set filament→flow rate to 1. Slice the model.
Switch preview color scheme to "Flow".
Remember the value
Set filament→flow rate to 0.5. Slice the model.
Switch preview color scheme to "Flow".
Compare new value with previous.

Actual results

The values ​​differ by a factor of four

Expected results

The values ​​differ by a factor of two

Project file & Debug log uploads

Note that REAL flows differ by a factor of two. The issue is about preview, not g-code
flow.zip

Thanks for raising this one. I saw the same, but I am glad to see the real ratio is correct.

[Rickthebig]

I noticed a similar, but opposite issue with the settings "Top surface flow ratio" and " Bottom surface flow ratio" - both need to be changed to a larger extend than expected, in order to achieve a minor change of the corresponding flow rate. I cannot quantify the deviation, but something is definitely wrong here too.
