Viewer hangs opening books for the second time

thiago.eec · 07-16-2021, 08:24 AM

I'm having this issue for a while.

Every time I open a book for the second time, it hangs on "Loading next section". If I rename the file (outside the library file), then I can open it again.
Since it looks like a cache issue, I tried cleaning the cache folder, and also changing its location using CALIBRE_CACHE_DIRECTORY environment variable, but nothing seems to work.

Also, if I open the stand alone viewer and choose to open a book, then this does not happen. I can open a book as many times as I want.

Windows 10 Pro 21H1 x64
calibre 5.23 64bits

This is not new for this version. It was already happening before updating.

Are you running from source?

No. Just a regular local installation.

And does it also happen when booting windows in safe mode?

Just found the problem:

I had set calibre programs to run using the dedicated GPU. When I removed this configuration, everything went back to normal. Maybe some driver update caused this, since it was ok until sometime ago.

Hi thiago.eec

Where's the GPU setting you modified? My problem isn't exactly yours, but it's similar:

If you type "Graphic settings" on your search bar, you will get there. But you can also go to Settings > System > Video > Graphic settings (roll to the bottom).

There you can choose an app and set it to use dedicated GPU (or not).

This setting can also be configured on your Graphic Card app. In my case, I had it set on both, so I also had to disable on both.
