I just wanted to post that with today's patch (Aug. 9th) it does look like the issue is solved, as per patch notes. I took four screenshots in a row on my main character, then hopped to an alt and no crashing.
Anyway, thanks for the time spent on this. I'll be honest when I say this did take a while to get patched in, but I do understand that having the fix done and then getting said fix moved into the patch schedule are two different things as well.
