    Hi,

    Recently i moved to work with QT5.13, after using QT5.12.1.
    Specifically i am using QtCore, QtGui and QtWidgets components.
    When i tested my app on a new fast computer, everything worked fine, when i tried an older slower computer, the API "dataChanged" is not returning correctly, causing my code to repeat some function calls, until i am getting a stack overflow. Is that a known issue? where there any changes in this API?

    i tried QT5.12.4 and got the same issue.

    thanks

      @shuga said in dataChanged API causing stack overflow when moving from QT5.12.1 to QT5.12.4/QT5.13:

      the API "dataChanged" is not returning correctly

      You may need to post some code snippets, we're not magicians...

      Please show how you're connecting such signal "dataChanged" and what the slot is doing. Also information about OS version and compiler used would be helpful
