I'm still not fully sure what to think of the new theme. I wasn't partial to the old one, but I can't say yet whether this is better or not, I will have to give it more time. At least the site's better to browse on phones, but I'm not sure whether a large portion of the user base necessarily was waiting for that or not.
That said, I will agree that changing the cursor is not very user friendly. I have my cursor set as I like on my computer, why does this site think it knows better what I want? That it isn't an opt-in feature is a bit ridiculous. It gives me similar feelings as forums having snow effects on during the holidays, it's cute for about five seconds, then it becomes an annoying, stupid gimmick that hampers user experience.
EDIT: And the fact everything is CC. I now know this already was a thing before the redesign, and at least it's clear now, but I'd very much like to be able to disable that for at least photos. Otherwise I'm going to pull all my photos from the site, and do external image linking as to preserve my copyrights on those photos.
