Images used for the Compact logo on the upper left of the nav bar appear blurred even when matched exactly to the CSS display size. It appears to be a Boost issue as the same thing happens with the latest Classic & Fordson themes. However, if I use the latest Moove theme, the logo image quality is much clearer. If I use the image in a the content area of a Page, Lesson, Book, etc, it looks clear and sharp.
Example: Image on the left is screenshot of logo with Moove theme. Same image using Boost is on the right. No matter whether I match the image size exactly to the CSS image height or using a 2 or 3 times larger image, the results are the same.
