when i set the white background,

but when i set the transparent background, text and line seems blurry

Make sure your application has an app.manifest and are using version 94.4.50

https://github.com/cefsharp/CefSharp.MinimalExample/blob/master/CefSharp.MinimalExample.OffScreen/app.manifest

is this a bug?

Impossible to say as you haven't provided any details.

It's important to remember that CefSharp is just one of many chromium embedded framework wrappers. The actual rendering is done in CEF/Chromium.
