Using calibre to read a Japanese ebook with vertical text bug

[Arilando]

I'm experiencing a bug when reading a Japanese ebook with vertical text. A significant part of the text seems to be disappearing in the left margin. Disappearing in the sense that part of the characters are only partially visible in the leftmost part of the screen. A part of the text is therefore unreadable.

Anyone know of a solution to this problem?

Use the beta from https://www.mobileread.com/forums/sh...d.php?t=331543

Are there any features implemented in the beta that prevent this problem?

@Arilando Yes, vertical writing support was added, fixing just the symptom that you described.

@Arilando Are you still having the same issue even with the beta?

[Arilando]

Yes the problem is still there, at least using the portable installer. The others wouldn't work because i'm on windows 7.

1. When you open the beta version of Calibre to open the book, what does it say on the bottom-left of the window? It should say "calibre 4.99.13 created by Kovid Goyal."
If it doesn't, you may be opening an older version of Calibre already installed on your computer instead of the portable version.

2. I've attached a free book I used as one of my test cases for vertical writing support. Does it exhibit the same problem for you?
If so, would you please describe in detail how you got to the issue? For example, did you use ebook-viewer-portable.exe or calibre-portable.exe? Once you opened those, what was the next step? And would you please attach a picture of the problem?

3. If the test book works fine, and you are sure that you're using the beta version, I would need you to send me the book you're having trouble reading and I can try to debug it locally.
