When using a PinchArea inside a Flickable, touch event handling starts failing when zooming in.

This looks exactly like the issue described in QTBUG-77629 for v5.13, but since that bug didn't show any activity since creation, I choose to create a new one for v5.15.0.

Reproduceable with the main.qml in the other qtbug and/or with the standard Qt examples.

The workaround mentioned on StackOverflow, i.e. adding a MouseArea under the PinchArea solves the issue for us as well.

(there's also an old report under QTBUG-58170 that might be related)
