    I've never seen this... maybe it's because you have a compositor running?

    I've done rebuilding packages with optimization options a very very long time ago (95-ties where that was hip to do). Performance improvement was really negligible, but in about 90% cases there was a...

    Could you give me the output of "xdpyinfo" from an installation of EMGD ? It might give me clues why the fullscreen flash doesn't work.

    When you run a compositor, Xv has always worked, it's when you don't run it that previously Xv stayed black.

    I honestly don't think there would be a huge difference in speed in GFX-performance between Fedora and Ubuntu since the driver is mostly the same. When you'd run a compositor, that will most likely...

    Xv is not 100% perfect but it works. The thing is I made it overlaying the video on the framebuffer, but without the color-keying that's normally used by proprietary nvidia/ATI drivers. The...

    that means we gain speed with EXANoComposite=false ? It would make sense, the option disables mmx/sse in EXA-code for compositing. It also means ubuntu ships xorg now with the option=true because the...

    You can always check if there is a difference in extensions using xdpyinfo. That is generally the place where software checks if something is supported or not.

    Do you have an idea why it breaks kwin compositing? Wrong detection or has something changed within Xorg and is ExaCompositing no longer supported (eg no longer doing compositing) ?

    Wasn't there a patch (originally a config option) to fix a crash with 10.10? That one could potentially cause a performance drop and something I was planning to look at too.
