OK, there are two separate things going on:

When I enable it, it shrinks the Name column to the minimum (instead of just all other columns and maximizing Name).
1. This is a bug. When you enable autosize columns for the FIRST time, it makes the width of ALL columns, INCLUDING the name column, minimal. Instead it should only make all other columns minimal and make the name column maximal.
Once you change a folder with the feature already enabled it works correctly though.

And as soon I change the folder, the checkmark on "Autosize columns" disappears again.
2. This is a separate issue, and was my own fault: I had folder views enabled, and had to manually modify every defined folder view to use the autosize columns feature. So this is fixed now.
However I observed two new problems, now that autosize works:
3.
The width of a vertical scroll bar is not taken into account when determining how wide the name column should be. this always creates an unnecessary horizontal scrollbar, whenever a vertical scrollbar is present. Actually, the issue seems to be something else. It also appears in folders without vertical scrollbars. It may be related to the changing width of the "Size" column. I am seeing in all kinds of different folders that the name column is often a little bit too wide so that a horizontal scrollbar appears. The amount by which it is too wide is different in every folder. EDIT: Yes, as soon as I remove the "Size" column, it seems to always work.
4. Autosize column should only be using the width of the CONTENT of a column, not its title. My "track number" columns are now much wider than needed because the word "Titelnummer" is much wider than the actual numbers in the column.
