--- Comment #13 from Eike Hein <h...@kde.org> ---
I did, and I see poor graphical performance that seems to be general on your
system, nothing that's specific to Kicker. In lieu of replacing your graphics
driver/hardware (probably the most practical solution), Wayland would probably
perform better than X11 on your system - at least some of the glitches I see in
your video are caused X11 being very poor at doing window mapping and resizing
atomically (yes, despite the existence of the sync protocol) - between Qt Quick
and X11 resizing the dialog window and the GL scene inside doesn't always
happen within one frame, and most likely due to poor performance or driver
bugs, it's especially bad on your system. Unfortunately that's nothing that can
be affected from the level of Kicker's code though (and we've already tried
pretty hard to optimize this in kwin/Qt Quick and even xcb by trying to use the
sync protocol in more creative ways, texture reuse, etc. without much success).
Wayland inherently fixes these kinds of problems by design though, so might be
worth trying if the Wayland session is already feature-complete enough for your
needs.
