I can't reproduce the problem, could you share the book you used in your video?

[mricgar]

I share a video playing in the test app with one of the available books. I think this will be more useful

Unfortunately I can't fix the problem if I can't reproduce it myself. It looks like a rendering bug in the web view.

[mricgar]

How can we help you?

[mickael-menu]

If you could share with me one of the book exhibiting the issue, maybe I can reproduce it this way. Otherwise try debugging the toolkit yourself to find clues.

[mickael-menu]

Also you could try using git bisect on the toolkit to find which commit introduced the issue, if it's a regression.

Good news, I wasn't looking for this but it happened on my device. The issue is the computation of the Readium CSS --RS__viewportWidth which uses an incorrect null width. I'll investigate some more.

 --RS__viewportWidth:calc(0px / 2.75);

[mickael-menu]

Could you check if this fixes it for you? #281

From branch fix/null-viewport-width

[mricgar]

Great! yes, in this fixed "fix/null-viewport-width" it no longer happens to me

¿Do you have an approximate date (months) for the next version is out?

[mickael-menu]

It should be pretty soon now, we're just finalizing the new Settings API for PDF and then we'll do a new release. A matter of weeks.
