Whenever I click an item in the Bazaar to preview it..... It only sometimes shows a portion of what it looks like, or in worse cases, it doesn't show the item at all. The view looks fine in your backpack but in the shop its either zoomed in too close or it doesn't display the item.
Re: Furniture not displaying correctly in the Bazaar
I have run into this issue myself, and it is very annoying when I am trying to decorate my (many) castles. Definitely a cosmetic issue, which I can definitely say for a fact is triggered by trying to click on many items. For example, if I click on each item on the page to see the preview, it begins to glitch out, such as the problem you have been facing. This issue has been around since I started playing in 2009, but hopefully KI will look into this if they can fix it. Try emailing the support group!
