I recently downloaded an ePub that is clearly in “Fixed Layout,” and I know that Calibre can't display it properly.
The result is indeed terrible (truncated lines, misaligned text, random font sizes, etc.).

I downloaded a free Microsoft app from their store called ePub File Reader, which displays the file perfectly. The reading experience is just as flawless as if the file were a perfectly formatted PDF.

My questions:

1. Do you know of a way to use this app to at least convert this ePub to a PDF? Apparently, it doesn’t allow exporting.

2. Is there a Calibre plugin that could do the same job as this app, perhaps using the same type of code, or even directly using the Microsoft app as a source?

3. Are there any plans to integrate support for reading Fixed Layout ePubs (which, unfortunately, are becoming more and more common) into Calibre? Or, at the very least, to integrate flawless conversion of these files to PDF into Calibre?

Thank you in advance for your answers.
