    impressed?

    I'm curious... How so? / Why?

But that is in cinnamon and i will admit - not the best captured video due to laziness (but it doesn't even matter if it was 'perfectly captured', all the compositing WMs seem to interfere with screencasting, at times... i can produce similar things, to varying degrees in ALL composited WMs (including KDE/kwin). All one needs to do is watch a few linux-related youtube videos and you are bound to see exactly what i mean...

    sometimes, you will see some random blue, artifacts, things not being drawn for a second ~ that kind of thing (which is something i do not experience on any Mac that i've ever owned, at all). That being said, it seems to be worsened in any linux environment, just by running say a VM with H/w acceleration and/or other OpenGL apps (some have no effect, while others seem to).

    qtcurve*-gtk* not just qtcurve: A configurable set of widget styles for KDE and Gtk

    I think kokoko3k's problem is in part qtcurve-gtk2, but obviously nvidia is part of the problem too...

    ..but i think you happen to be confused about Cairo OpenGL support, in the second part of your answer... Cairo OpenGL support is marked experimental ~ but isn't that refering to the '--enable-gl=' build flag, which enables the experimental Cairo-OpenGL backend?!? (which fyi is disabled by default, on pretty much all distros and also in the cairo-nvidiablob package that he is using)...

    @Kokoko3k - Do you experience this problem, when NOT using qtcurve-gtk2? (it also appears to have a downstream patch for cairo).

    I didn't make a specific comment on cinnamon being able to do things that KDE can't. KDE is extremely customizable, it's just too buggy for my tastes. I don't like it's animations that slow down moving windows, nor do i like windows in expo exhibiting buggy behavior, etc.

    Funny that you mention the start menu ~ I don't use slingshot (in cinnamon), and besides KDE's QML menu is actually fairly nice (not that i would use it either, though). I mostly use gestures via 'easystroke' for launching apps, mapping hotkeys, etc and use AWN/dockx for my dockbar / quick access to apps / window/app switching/management. ie;

    http://www.youtube.com/watch?v=0APPcFRDVSw

    the frame rate is a little off (i had to reduce in order to capture cinnamon's expo/scale), but i think you'll get the idea. (note: it is available in 720HD, for crispness)... There isn't much need for a startmenu (even though there is one, standard gtk2 style). Most navigation, launching apps, etc is done using my stylus (wacom tablet) + gestures (and/or via AWN) and i don't use a mouse at all (haven't for years!). Cinnamon panel has been reduced to a systray / notifications area, transparent and hidden (as shown at the end).

    anyway, to me Cinnamon feels much cleaner than KDE (with less bugs!), but to each their own

    What are the things you can do with cinnamon that others can't do with KDE? Is it the start menu?

    like this:


    Then install cairo-nvidiablob from aur and scroll it again.
    For me, vanilla cairo is jerky with the blob, smooth with everything else, i just tried again.

    Well, they should not use this, no matter what GL version is the baseline. And I'm pretty sure they don't. glDrawPixels is a very deprecated and very slow operation. Some old legacy applications might benefit from this optimization though. But if you use glDrawPixels (or its cousins) in current code, you should be thorougly beaten with a stick.
