Unable to load images properly using Qimage's load()

[houyawei]

Use Qimage's load() to load images, print log load() and return success, but the program will get stuck in load(). If this part is removed, it will run normally

But on my compilation host, there is no such issue on the other laptop. There is this issue on a poorly performing mini host using Qt5.9.3

QImage img;
img.load(pic_name);
int WindowW = this->width()*0.9;
int WindowH = this->height()*0.9;
pic_label->setGeometry(0, 0, WindowW, WindowH);
QImage scalimg = img.scaled(pic_label->size(), Qt::KeepAspectRatio, Qt::SmoothTransformation);
pic_label->setPixmap(QPixmap::fromImage(scalimg));

You should check the image if it is correct and can be loaded by other image viewers. A backtracce would also help here.

After compiling with Qt5.15.2, the images can be loaded normally, but the processing speed is slow on the mini host and runs normally on other computers

on the mini host

What is this?

This is a small computer, and the issue of replacing the computer host has been resolved. When the image replacement speed is too fast, the small computer cannot display it
