I regularly run into issues with the number of columns of my fences. I've got several fences with 3 columns and a few with 2.
Between startups, the number of columns decrease by 1, thus I get two columns of icons in a 3 column-wide fence. Slightly stretching the fence snaps everything back into place (as if i change the width from 2.99 columns to 3.00). It happens sometimes on the 2-column fences as well, from 2 to 1 column.
I don't think I've seen this problem on all fences at the same time. Has anyone seen this as well? Running version 126.96.36.199.
