Editor not working
I have W10 and Calibre 5.6 The Calibre editor and viewer does not show me the content of the book. They will open but only a blank window is displayed.


Greetings and thanks in advance

Please run the following command from the Windows Command line and post the output.

It should open the viewer and display a list of books to read. At least that is what happens here.

Code:
calibre-debug -w

I think that one of the lines says "Using calibre QT style: true" - it is very hard to read a picture, it would have been better to copy the text into a reply.
Mine says false there.
From the little output given by calibre, you may wish to try changing the qt style back to system default. It's in the Preferences - Look and Feel section in the main Calibre program.
However it makes no difference here how that is set but that is the only difference to my debug output.
Perhaps some on else will have an idea of what is going wrong.

Your problem appears to have nothing to do with saved searched - so I moved it into its own thread.


Did you read post #2 - when the editor opens a book the code window is empty until you select a file, viz:

I'm wondering if this is related to the various blank screen in viewer or editor which seems to be tied to the video driver reported a few months back.

@FLeCos, what video card and driver version are you using?

This will be a problem with your GPU drivers. Try updating them, if that doesnt fix it, turn of hardawre acceleration for Qt WebEngine (which isthe component the viewer and edito use) as described here: https://doc.qt.io/qt-5/qtwebengine-debugging.html

Are you running Calibre on a laptop with dual video cards? If so, switch Calibre to run with the other video card. I gave this same advice to someone else and it solved the same problem.

You don't have the latest graphics driver. Not even close given the version number and date. Here is the latest driver for your GeForce GTX 760. This drive was released February 27, 2020.
