QQuickView - Bad rendering performance (only!) in fullscreen mode



  • Hi all,

    I have a QtQuick UI which renders really good until I run it in fullscreen mode (showFullScreen()). As soon as the UI covers every pixel of the underlying Desktop (Debian wheezy), the animation performance decreases enormous.

    Actually I run the UI with Qt::FramelessWindowHint in 1920x1079 (instead of 1920x1080) as a workaround to keep the animations fluid... But this isn't really satisfying.

    Does anybody has an idea?
    Thanks in advance!
