BUG - Non-standard album art not displaying well in 5.1b1

Hope this is the right place ... cannot see anywhere specifically for bug reports.
OS Windows Home Server v1 (ie, Windows Server 2003 32-bit)

Browser Chrome v39 on Windows 8.1 64-bit
I've noticed since installing 5.1b1 that any album art that is non-square doesn't seem to display correctly; for instance, I've got lots of audiobooks where I've set the cover image to the book cover itself. This seems to throw off the renderer (see attachments). Also, when I use IE11 to view the same page, all the albums show one per row - ie, they are listed vertically rather than as a grid (see attachments). It still has the image aspect issue too, though.
Let me know what else I can attach to debug ...
