There's a problem with setting blur effect for QCalendarWidget. It's like the calendar doesn't repaint correctly its contents. I set the effect to enabled, but the widget doesn't get blured, but then when I resize the widget, it kind of gets blured, but not really (only some parts and only at some moments).
I tried it under linux and windows with very simple test application:
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QGraphicsBlurEffect>
#include <QMainWindow>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
private slots:
void on_checkBox_toggled(bool checked);
private:
Ui::MainWindow *ui;
QGraphicsBlurEffect* effect;
};
#endif // MAINWINDOW_H
#include "mainwindow.h"
#include "ui_mainwindow.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
effect = new QGraphicsBlurEffect();
effect->setEnabled(false);
ui->calendarWidget->setGraphicsEffect(effect);
}
MainWindow::~MainWindow()
{
delete effect;
delete ui;
}
void MainWindow::on_checkBox_toggled(bool checked)
{
effect->setEnabled(checked);
}

Am I doing something wrong, or is it a bug?
