After the update to 3.4.1 the inserted images look good inside the WP editor, keeping the right alignment, while writing a NEW post. But images are unwrapped in preview mode and after publishing. The caption to an image goes as a separate line, close to the image. No frame around an image.
The images in the old posts and pages look OK. If to edit even a word in the post/page and update - the images go broken the same as in new posts.
