The reason that the coffee cup doesn't fit well within the image is because the render box for the inpaint area is such a small part of the image - anything generated is done so only within the context of a) what is not denoised i.e. the original image and b) what SD can actually see (within the render box). For high denoising strength you generally want a larger render box, otherwise it's easy to lose context. But what if you only want to change a small area? No problem! The render area is created as a bounding box that contains all the inpaint area you've selected - so, you can increase it by adding tiny dots of inpaint area to the scene. If you make them very small then whatever is behind it will generally be unchanged once rendered, so only the main area you've selected will be altered - but the dots will still count towards the bounding box. In the example given, I would put one dot above and to the left of the first coffee cup, and one at the bottom and to the right of the table. That way, what is rendered will probably adher more closely to both the focus (the blur on the coffee cup) and orientation and size of the table. For lower denoising strength (0.5 or below I'd say) it will generally be able to glean the context from what remains of the original image, but for anything higher I get much better results with this method.
