delay in executing widget program

I have a Main window with push buttons to open other windows, as shown below:

enter image description here

Here both in Program window and Logs window , I have a back to main button which can take to the Main window.

In the Logs window at present I'm having a real-time display of sensor.

Everything seems fine if I start Logs from Main in the first time

But, if I goto Programs -> back to Main -> Logs the Logs window is getting too much delayed.

This is how I go back to Main from Program

void stageProgram::on_pushButton_shoulderControl_clicked()
{

    this-> close();
    StageOneMain *newPatient = new StageOneMain(pLabel);
    newPatient-> show();
}

Logs from Main

void StageOneMain::on_pushButton_logs_clicked()
{
    this->close();
    window = new ShoulderControl(pLabel);
    window -> show();
}

Anybody see some issue here?

I would suggest that you use QStackedWidget. It is good for navigating through different "pages". You can add 5 pages to the stacked widget. when you click on a button and need to change to the respective page you do stackedWidget->setCurrentIndex(indexOfThePage); for example, the function to go back to main menu can look like stackedWidget->setCurrentIndex(0); for further reference you can see this page of the official Qt documentation.
