Ok, after some further testing I'm going to go ahead and say in my experience, this bug appears patched.
My uses with the GPU lock, while similar in symptom, appear to be a secondary unrelated issue. Interestingly when doing a hard reset into gnome-shell, I experience the issues above. When booting into unity and then logging out and logging into gnome-shell, I experience no issue.
