Ebook Viewer issue
I'm using Calibre on Windows 11, but the Ebook Viewer doesn't work. When I click on its icon in Calibre, a window opens, but the ebook content doesn't appear.

Is there any solution?

Thanks.

Most frequent answer is to update your graphics card drivers.
Caution: Only use the PC manufacturers site, the card makers site, or OFFICIAL Windows.
There are a ton of 'driver' sites out there that just might give yo a little extra

I have updated my graphics card drivers, but the problem persists. Thanks, theducks.

Uninstall Calibre (your Library and settings remain) DO NOT use an Uninstaller /Cleaner.
Get and install 7.16 from the OFFICIAL Calibre download page
Previous release link is below the Donate section

Try adding the following environment variable.
Code:
QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu"
That will disable the video card driver for calibre and hopefully allow it to work.
