I have the same issue drawing a background in a QFrame using border-image. For some reason cpu usage goes up to 40%. The original image is 1600x1400 and I need to scale down to 1024x768. Is there any other way to scale background images without killing performace?


#loginFrame {
background-color: #005072;
border-image: url(/usr/local/share/nxtop/Images/backgrounds/lockscreen.png) 4 4 4 4 stretch stretch;
}
