When viewing a PDF in a QWebEngineView or WebEngineView, the zoom is broken:
- When opening a PDF the default zoom is OK
- The 3 zoom buttons (+, -, auto) are not visible
- Attempting to zoom using the mouse wheel sets the zoom to some minimal value: the whole PDF looks like a postal stamp and there is no way to zoom back in.
It was working fine with 5.15.1
This can be easily reproduces by using the quicknanobrowser example.
