Paginated mode blocks reading a book on Windows at least

[manuellagrand]

reading is blocked after few pages in paginated mode (approximatively 2 pages) depending on the os that is used.
with MacOS and Ubuntu 16.04 no problem, but on Windows 10 and Ubuntu 18.04 the reader doesn't work like it should.

What is the exact source / build of the app (develop branch, or prebuilt installer?) I need to see/check the precise navigator version in package-lock.json to make sure the Electron/Chromium fix for left-right arrow keys is included.

[manuellagrand]

the source is develop branch and navigator version is 1.0.26

Hello,

I think this issue is related to a second display glitch

On reader :

When I lower the height of the window, then I raise it to the same height as before.

That display the previous "page" of book and not the same.

I think we can lost the postion in book.

What do you think ?

Ubuntu lts 18.04
r2-navigator in 1.0.26

To narrow down the problem, is there some log we could add to the software, so we can check something?

I am not able to reproduce this on Windows 10.

PS: I am using the develop branch (well, this actually: edrlab/thorium-reader#323 )

[manuellagrand]

the paginated mode issue seems fixed on Windows 10.
Now, it's the scrollable mode on Windows 10 that blocked book reading.
I am using the develop branch

On ubuntu lts 18, it's opposite of the Manuel answer.

Paginated mode is blocked at each new chapter
whereas it doesn't blocked in scrollable mode

[danielweck]

I cannot reproduce (scroll or paginated) on Linux (Lubuntu 18.04)

I test with various EPUBs, usual suspects: Wasteland, AccessibleEPUB3, ChildrensLitterature ...
What EPUBs are problematic in your tests?

[danielweck]

Regarding "loosing the reading location": yes, this is a problem we had in Readium1 as well. Because we track the upper-left corner of the document text in order to estimate the user's reading position, when the window is resized there is a side effect of "walking backwards". Note that we also track the reading location when the user interacts with the mouse or keyboard in the document, but this isn't related.

I posted a separate issue: #43
