Open in QtCreator:

/Users/jwb/Qt/Examples/Qt-6.4.0/pdf/pdfviewer/CMakeLists.txt

Compile and run the app.

Use the selector to go to page 3 (the page with the tiger, for example, as there is more detail to see on that page).

Pinch-zoom in and out on the laptop's trackpad, zooming way in and then out.

Eventually the pinch zoom will cease to function and only a restart fixes the problem.

The problem seems to occur on zoom in and not zoom out.

For example, I experienced the problem occurring at scale 16.77 (other scale values possible). In my case, scrolling left and right on the trackpad (not on the scroll bars) continued to function although the pinch zoom did not.
