It seems like the mixin is getting the wrong size for the preferred
width of the columns.

Because it's a virtual list, that must somehow affect the call to
SetColumnWidth(col, wx.LIST_AUTOSIZE) by preventing it from looking at
all 1 million rows.

Different things happen on windows and GTK (both using 2.7.8.1):  on
windows the call to SetColumnWIdth only looks at some small number of
rows (perhaps only the first).  On GTK, it is always returning 80
pixels.  I haven't looked at the C++ source to see what's going on.

I don't know what the best solution is -- take a random selection of
some subset of rows and use those rows to guess a preferred size?

Any ideas?
