The usual suggestion would be to update your video driver if an update is available. calibre uses QT for it's video interface and the people behind QT seem drop support for older video drivers rather enthusiastically.

One alternate suggestion is to add an environmental variable QTWEBENGINE_CHROMIUM_FLAGS and give it the value --disable-gpu.

Do a search for environmental variables which should open System Properties. Click on the Environmental Variables button then under System variables, click on the New button. In the box that pops up, enter QTWEBENGINE_CHROMIUM_FLAGS in the Variable name and --disable-gpu in the Variable value then click OK. You may need to restart your computer before this will take effect.
