i am also having this issue, this is the only other mention i can find of it so far!
it only happens when i create custom thumbnails, but all of a sudden it’ll put in a break in odd spots-
for example, if there are 10 images in a row, it’ll display 10, then 1, then 10, then 1, etc.
but if i re-create the thumbnails to the automatic cropping, it goes away and displays normally (10, 10, 10, etc).
changing the number of columns in the gallery settings hasn’t helped- it does change the spacing, but the number of thumbnails per line (10,1,10,1) does not change.
i’ve investigated the z-index element, but i don’t know much about z-indexes and what i was able to find in the code didn’t seem related to this gallery sorting issue.
would love to hear from anyone else who was able to work around this.
