    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.

    What's qtcurve got to do with what you're describing? Also note that Cairo OpenGL support is marked as experimental, therefore not expected to work flawlessly to begin with.

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

        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

        SIDENOTE: I wonder if we are ever going to see sceencasting NOT producing artifacts, in composited environments in linux (particularly if you happen to also be running other gl apps.... it happens in pretty much every DE/WM (compositing WM) to some degree or another. it's super annoying - and i wonder if it is a driver problem or DE problem?

          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).

            erm, why would i need to describe what they look like, when there is a video link, in the very post you are responding to??? ~ that shows at least 2 examples...lol (there is one part when gedit paints funny - at the end, another when AWN isn't drawn and a couple of flashes). 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).

              impressed?

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

                Yeah, i was never really interested in cinnamon until recently, but now that it has matured a bit - it seems to work very well. As far as what you see at 21 seconds in, that isn't Cinnamon (i think) you are referring to 'Lightworks' (video-editor) that is running on linux - in it's alpha program, that has been mentioned in many articles here ~ i got into the alpha program and have been testing it! ... I've already had some bugs fixed I assume that's what you are referring to (blue screen?) because the only other desktop is MacOSX in the video.

                  That's what i thought. You obviously recognized MacOSX (VM), as most people (unless they live under a rock) would, which left only Lightworks..

                  Lightworks IS pretty much a desktop environment in in itself, aside from being a video editor. It has it's own toolkit, dock, workspaces/rooms and window management... however, in using it daily - it actually reminds me of Gnome-Shell more than unity. One big similarity to GS is having dynamic workspaces/rooms for setting up all your windows/viewers/timeline/etc (and it saves your layout, in your project too - which is quite useful!). But yeah, the dock on the side is Unity/GS-ish - very handy for quick access to things though (and your rooms are available via a drop-down menu, which is easy access as well).

                  i'm actually working on a screencast right now in lightworks, to showcase some software that i have contributed _core_ ideas to, a patch and done all of the initial testing for. I'm going to upload to youtube when i am done

                  it's an app called WiiMidi and is pretty powerful software (for interacting with wii controllers, in linux), with some cool features; like converting Wii signals into MIDI (including raw midi), being able to control visual feedback from the wii remote's LEDs (including animations per control+), mapping multiple controls to a single button (including being able to cycle between each), being able to switch midi channels 'globally' (which in my case, means i can map the same 12 + 15 buttons to control different functions, depending on the midi channel used - 16 channels X 27 buttons = 432 mappings! (not including 'cycles') It absolutely slaughters/dwarfs what you can do with Cwiid alone (which is the library that supports wii on linux).. ~ it can also be used to control your desktop (by converting midi to keystroke via aseqkey), which allows me to use my hacked wii controllers in Lightworks to control things, or i could map controls for my DE hotkeys, or any other app(s)

                  http://roland.entierement.nu/pages/wiimidi.html

                  anyway, i digress But do give Cinnamon a try, it is killer! (and is smooth with Nvidia)

                    As ninez said, qtcuve applies to gtk too (qtcurve-gtk), and as firefox uses native widgets to draw buttons, input boxes and so on, the slower is the system to draw them, the slower will be the scrolling.
                    This has nothing to do with cairo-opengl; nvidia in the past said they fixed the missing "gradient drawing" acceleration,that's why, some distros patched cairo to just rely on the cpu for that.
                    If i disable that patch, i get very slow scrolling; that's all.

                    Qtcurve exposes the issue massively, but other styles seems to be are affected too:

                      I'm not really sure about that The credit surely should go to the developer. (Roland Mas, A debian developer) I just took his old (python) code and added a 'proof-of-concept' for animated LEDs, then suggested global midi-channel switching and adding a few other options for midi. He then decided (after we had implemented and tested our ideas), to rewrite a chunk of the code, which i assisted in collecting all of the (hex) codes for wii devices. But all of the bit-juggling and implementation details he looked after.

                      anyway, I got an email last night with a new version (that supports the classic controller too), so i have to re-shoot parts of my screencast now. (but i don't care, since i wanted full classic controller support).

                      it is pretty amazing. it's actually (imho) better than most of the other wii software for linux, win or mac in many ways. (ie: better than osculator, pd-l2ork, etc) it's really easy to configure and has (potentially) a lot of different uses. Aside from being used to control a desktop / apps (if using aseqkey) and aside from (me) using it to control a wii-based midid foot controller, I've also been experimenting with using it as a 'session controller' ~ where i map the buttons to control switching presets (on every synth/module) that i use. (ie: i can map 1 button to change all of my presets/program changes at once - which is handy when jamming live. I can just map a key for each song / set of presets, for fast switching

                      Yeah, cinnamon is good stuff

                      I guess 'unico' engine must not be affected much. (which is what my theme is using).
