Calibre freezes after opening a book in Linux Mint 20.3 (6.8.0 calibre)
Hi.
Sorry for my bad English. I am using Linux Mint 20.3 and 6.8.0 version of Calibre. It does not open a book. It's just freezes while loading. Here is video

Can somebody help me with this issue?
Tried to find solution, but did not find anything
Thank you.

No problem for me with the same operating system. Does it happen with all the books or with some?

It will be GPU driver issues. Update your GPU drivers or you can try turning off hardware acceleration as described here: https://doc.qt.io/qt-6/qtwebengine-debugging.html

It works using both mint 20.2 and mint 21 on my system. Check out this thread on hardware rendering/acceleration disabling.

Probably it's driver issues yes. My laptop from 2005 with GPU GeForce 7000M / nForce 61 and has no new drivers. Only old nouveau driver version.
I am sorry, can't understand where shoud i type "--disable-gpu", in linux terminal?

type in:
