If you type a query in Google Image Search, click on the search button, scroll the page, click on the Google logo, type another query and select the "images" option, Google scrolls to a random part of the page. For example, it could scroll to the page 57.
Another issue is that Google's large thumbnails for PNG files are sometimes pixelated JPEGs.
Clicking on the "more" link in Google's sidebar refreshes the page and doesn't show additional Google services. When you go back to the results page after clicking on the results, you need to wait until Google scrolls to the right position and some of the images are loaded again. Scroll the results page, resize the browser's window and you'll notice that Google readjusts the images and jumps to the top of the page.
The new interface has too many bugs and should have been tested more thoroughly before being released. Google offers an option to switch to the previous version at the bottom of the page, but it's not persistent.
