MY blog was doing the same thing, the flicker and no place to comment. SO decided to try to fix my own and i think i did!!! Went to 'design' then to 'settings' then to 'posts & comments' then i changed the comments from embedded to pop-up!! and be sure to SAVE... This makes a new page with just the comments to the left hand side of the screen rather than a box at the bottom of the comments on the same page as the blog. AND hopefully this works for everyone, if not let me know!!! Please!!!
