I got this one off Freecycle and thought I’d use it as a secondary backup for all my videos music pictures podcasts and books in place of my primary desktop. Since it was a clean install I just started over and tried it on the untouched windows 10. Again it worked flawlessly. So I figured it must be caused by something I’d added or removed before I installed the Calibre program. Started out adding drivers. I’m pretty sure I found the issue but I don’t know what the resolution would be. It has to be my video driver. Calibre hates my AMD Radeon Vega 8 Graphics card it seems. I used the AMD cleanup utility to remove the most current driver and tested the other Vega drivers going down in chronological order. I finally had some what success with the Radeon Software Adrenalin 21.6.1 Driver Version 21.20.01.14 for Windows 10 (Windows Driver Store Version 27.20.22001.14011). I say somewhat because the hang will happen like every 20 times instead of every time the editor is launched. Then when I close the not responding box I get a strange buzz sound. I checked out some previous posts and read something about using Qt WebEngine Developer Tools to turn off hardware acceleration and Set the environment variable QTWEBENGINE_CHROMIUM_FLAGS to the value --disable-gpu and then reboot. Sadly that read like Latin to me so I didn't attempt those workarounds. Also read and tried the workaround Rename or delete the file tweak_book_gui.json which stores the editor settings. It just kept reoccurring. Any other ideas?  |
See

For Variable name use:
Code:
QTWEBENGINE_CHROMIUM_FLAGS
