[Solved] Why is text scrolling choppy in Qml?



  • Hi,
    A perfect example is the [Qt Quick Examples - Text -> Banner] on the Welcome Screen in Qt Creator. I'm using 5.2.1 and I'm developing on an i7 with a high end video card. The text is being visibly redrawn every half second or so. Is there any way I can get a smooth text scroll in Qml? Does it have something to do with refresh rates perhaps? I don't get it.

    thnx

    Brian



  • Okay, I had to replace the video driver on my Fedora 20 install to take advantage of the proprietary nvidia card and enable vdpau/vaapi ...

    Here is the guide I used in case anyone needs to do this ...

    No more choppy animations. Plus my video looks much better now too.
