This has bothered me for the longest time. Move texture so it doesn't overlap. I'd initially had a test for isPaused, but jumping texture bothered me.
#include <QApplication>
#include "mainform.h"
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MyWindow *mainWin = new MyWindow;
mainWin->show();
return app.exec();
}
