@maximesunnen the outputs look correct to me, we can try to help if you provide additional context or explanation of the expected result in each case.

[maximesunnen]

@djhammill so for you the minimum is located at the intersection of the red and black line in the last 2 plots? The valley is located more on the left for me.

[djhammill]

Mindensity uses adjust = 2 while geom_smooth uses adjust = 1 for the kernel density estimates. I suspect that if you set geom_density(adjust = 2) the locations will line up better.
