    Default KDE's KWin To Receive Performance Improvements

    Phoronix: KDE's KWin To Receive Performance Improvements

    Next month's KDE SC 4.9.2 release will be slightly faster with the KWin compositing window manager while more performance optimizations for KWin will land in KDE SC 4.10 come late January of 2013...

    that sounds promising

    any numbers or experience with
    According to the callgrind logs after the change this improves the performance quite a lot.

    Last time I've tried kde 4.9, kwin showed tearing in the upper portion of the screen, using nvidia proprietary, just like mutter or compiz.

    Mutter and compiz fixed that, and I would like to see that fixed in Kwin, because it's a very good compositor, and the only one that shutsdown effects completely while running fullscreen apps.

    In fact each call caused two dynamic casts to check whether it is a specific sub class...

    4.9 actually got worse for me when it comes to moving windows around. There's always a slight lag between where the mouse pointer is and where the drag point on the window is. It's a minor issue, to be sure, but annoying nonetheless. I hope it's fixed in 4.10. Maybe the translucency thing will take care of it.
