    Sorry for the dumb question: did you contact the KDE team? Did you file a bug/wishlist report? What did they reply?

    Or maybe it's because you have EXAvsynch on. It might be just me, although I'm keen on doing some benchmarks, but I kind of notice that switching the option on and off makes a difference in resizing windows and switching between windows.

    Does anyone have any benchmarks on this already?

    There's no reason to use EXAVSync if you want the fastest performance. It stalls the engine waiting to the vline to avoid tearing for EXA rendering. It has nothing to do with Xv, that is handled separately.

    Yeah, but I want tear-free and fast performance . Otherwise I need to restart X each time when I switch between them.

    I don't have EXAVsync enabled; the only option is "Accelmethod" "EXA".

    Am I seeing tear-free display & XV because of not using compositing?

    The Xv vline stuff is handled separately from EXA. Same process though.
