I do a lot tests, and find that Linux dont encounter this bug.
The version of my linux is the lastest linux mint based on Debian 12.
Cablire is installed by flatpak, its version is 7.4.
And, in window, I find some Clues.
First, Only when The end of a chapter (crosssponding to a xhtml) ocupies two pages on one screen, it will appears two blank page on the next screen.
So, How to find out this bug?
By change margins of the page to contrl the end's position on screen, i find that
The end of a chapter ocupies one pages (the left page) on screen, the blank page just disappear, and the next screen is next Chapter.
Attention, Must press PAGE DOWN to PageDown.
When press RIGHT to PageDown, The blank page always appear.
