Description
Hello!
I have problem with opening the dialog when touchscreen connected. The software is an HMI visualization for PLC controller. Large number of objects are loaded into the QML side which was created in C++.
My investigations point me that I only have problem with the Dialog which have TextField.
As I understand the textfield, invokes some touch functions, so I think that's why has in connection with the touchscreen.
I was trying to make a minimal example, but without luck. I can only send video from it.
with touchscreen:

Once the faulty dialog opened, after a second try, the opening works normally.
Other dialogs acts the same. First try hang, second try works.
without touchscreen(works as expected):

I have other dialogs(loader based) in the software which is created dynamically, in that case this behavior not occurs.
How can I debug this problem? How can I see that which part(inside Qt) hanging the software?
Thanks
