Featured Images being blurry

I'm mapping the image box to the standard [post_thumbnail] however each image is extremely blurry and does not represent the image true quality. Am I missing something here or is this a bug? I have tried scaling the image to different sizes however this does not improve the quality.

Hi,

[post_thumbnail] shortcode using "thumbnail" (150x150) image size by default. You can change it by adding "size" attribute to shortcode:

[post_thumbnail size="full"]

Default Image sizes: thumbnail, medium, medium_large, large or full but it can be used also other custom registered image sizes.
