Hey i have same problem. I use qt 6.3.0 pyside6.
This bug occurs when you open new dialog and set atrribute qt::WA_DeleteOnClose

For temporaly i fixed this issue, i removed this attribute and set all dialogs like a main class attrubute.
So dont remove any c++ object and it ll fixed but i think its awful fix. I need solution too but i couldnt find anything about this.

As I now understand it there is no easy way to recognize gestures inside the c++ part of a Qt Quick 'QQuickPaintedItem' inherited class, is that correct?

I need both pan and pinch in my c++ class so if i dont want to write my own recognition code should I then inherit my class from both 'QQuickPaintedItem', PinchArea and Flickable? that doesn't seem right? (besides that they are declared in private header files like qquickpincharea_p.h)

found the same request (also without an statisfying answer here:

Hi,

You have several wiki pages about Qt and the Raspberry Pi, see here for a start.

Sorry, I haven't used wayland yet, can't help you currently
