Hi all,
I have an application on Linux.
I make a screenshot as follows :QScreen *screen = QGuiApplication::primaryScreen(); QPixmap pixmap = screen->grabWindow(0); bool result = pixmap.save("sc,"PNG");This works correctly when I use CentOS-7 but when using Rocky Linux 9, I have a black screenshot.
Is there anyway to resolve this problem ?Thanks in advance !
