These are my pc's specifications: Intel Core2 CPU 6300 1.86GHz || RAM 2001 MiB || ASUS INC. P5B-VM nVidia G73 [GeForce 7300 GT] [10de:0393] {nvidia} I had a similar problem with gnome too which is partialy fixed. https://bugzilla.gnome.org/show_bug.cgi?id=709036 Reproducible: Always
Could you describe the glitches you see? Does it happen with compositing disabled or using only XRender compositing type? Also, please add output of this command: qdbus org.kde.kwin /KWin supportInformation
Oh, there is a video linked, that pretty much describes the issues, still the technical information requested in comment #1 are needed.
I think this command Is not correct. OS does not accept it. qdbus: could not find a Qt installation of '' I have also add that I tested opensuse 13.1 whith the same issue and now I'm downloading Mageia cauldron. It's weird but when I tested kubuntu 13.10 when was in beta state it hasn't this issue.
(In reply to comment #3) > I think this command Is not correct. Command is perfect, OS is broken ("incomplete") See whether you got "qdbus-qt4" and otherwise install the package that contains qdbus on ubuntu (That *should* be qt or qt4) For the beginning at least provide the ouput of "glxinfo" and then run "kcmshell4 kwincompositing" and try setting the compositor backend to xrender.

Xrender compisitor backend does the trick. Also, I tried Mageia 4 alpha 3... There was no issue. I installed "qdbus-qt5" and "mesa utils" for glxinfo.
Kubuntu is with nouveau preinstalled but mageia was with nvidia driver preinstalled.
> OpenGL vendor string: nouveau > OpenGL renderer string: Gallium 0.4 on NV4B > OpenGL version string: 2.1 Mesa 9.2.1 > OpenGL shading language version string: 1.20 You might want to try the nvidia blob (304.xxx should still support your GPU) or (if possible) updating to MESA 9.2.2 If you've now "qdbus" available, please still provide the supportInformation (with troublesome GL compositing) -- Most likely driver bug, eventually running into GLX_ARB_create_context troubles with MESA
I have qdbus but it says the same error I wrote in comment #3. Can I do something for it?
Seems to be a Ubuntu thing: https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/1177823 Comment #5 there has a promising workaround and the other solutions are to install qt[45]-default qttools[45]-dev-tools # [45] likely meaning 4 OR 5
setting to upstream - not much we can do as it's a live CD.
I am so sorry, system didn't let me install those packages and a gave up. It was difficult to navigate the ui this way. Opensuse 13.1 continues to have this bug. Can I install kubuntu without this bug if it is resolved downstream? What "setting to upstream" means? Thanks in advance.
You can install about any distro as long as it provides your the nvidia binary blob and be pretty sure to not encounter this issue (by using the nvidia driver instead of the nouveau one) "resolved upstream" is twisted - Martin marked the bug downstream ("distro") because the live system bundles a trouble making driver. The issue about missing qdbus installation is completely orthogonal to this - you just got to install the package that ships the binary. Distro hopping won't help you the least on this.
kdelibs (4.11.3) in fedora 20 and openGL 3.1 compositing type solves the issue on nouveau.

Since the chip/driver according to the glxinfo you posted doesn't support the OpengGL Core profile anyway, i'd simply try to avoid it. Ie., set compositing to OGL 2.0 and (from other bugreports about incapable HW) then rather reboot and see what happens.
Oh, I see.It seems GPU just showed it's age.
