Please share the following:
- Your store's url
- If your store is password protected, share the password either here or by PM
- Theme you are using
When you say images in the slideshow are super blurry, are you referring to this?
This is how the image is displayed while loading a larger image. After a short time I see the image perfectly sharp:
The Debut theme does not have any section names "product carousel".
Was this custom coded in your theme or added by an app? If this is the case, I cannot help without access to your store's code. Is it ok to request collaborator access?
