EPUB to MOBI (AZW3). Black SVG images with CSS styles

[uka]

Is there a way to keep SVG styles inside CDATA tag?
If debugging is enabled they are present in "input" directory and disappear in "parsed" directory. When I use kindlegen CDATA tags are keeped and images looks good on reader, when they are removed SVGs are black.

I tested it on Paperwhite 3 and Kindle 7. I attach screenshots.

Don't convert to both. Convert to KF8 only.

[kovidgoyal]

According to the conversion log you are converting to joint MOBI, not azw3. Does the problem still occur when you convert to only azw3 (which will not cause the SVG files to be rasterized).

I noticed that happens when I send file to Kindle by e-mail. When I transfer mobi file attached above via USB SVG images looks normal.

[kovidgoyal]

When you send books by email they are re-processed by amazon. calibre has no control over that. Stick to USB transfer as much as possible.
