The first time this happened, I had sorted by some column I hadn't sorted by before during that session, and then quickly scrolled down a long way. It took a loooong time for the text and images to appear.
The second time, I had sorted by Rating (which I also hadn't done before). I don't remember if I scrolled, but I do remember that I had to sit waiting for over a minute -- which is an awful lot too long.
The third time, as you can see, I had sorted by Edition, filtered for 'edition:e', and expanded. I gave up after about five minutes, when it still looked like this.
The first two don't seem repeatable once the grid has populated once, but the third is. Could be related to BUGS 5.2a RC1: Edition column.
Note: I'm repeating it as I write and Logos is only using 600 MB of RAM, I have almost 1 GB free, and there isn't much CPU activity going on.
