this is how it looks like when i'm moving my icons: ftp://blinkeye.ch/gentoo/screen.png
the traces only disappear when refreshing the desktop. i have no idea why this is happening or how to work around it. i had this very same behaviour some month ago with the theme plastik - choosing a different theme worked. i'm open for any ideas.

i use the following versions:
Code:
# emerge -p xorg-x11 qt kdelibs /usr/lib64/X11/rgbkdebase gentoo-sources nvidia-kernel nvidia-glx

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild   R   ] x11-base/xorg-x11-6.8.2-r2
[ebuild   R   ] x11-libs/qt-3.3.4-r3
[ebuild   R   ] kde-base/kdelibs-3.4.1-r1
[ebuild   R   ] kde-base/kdebase-3.4.1-r1
[ebuild   R   ] sys-kernel/gentoo-sources-2.6.12-r10
[ebuild   R   ] media-video/nvidia-kernel-1.0.6629-r4
[ebuild   R   ] media-video/nvidia-glx-1.0.6629-r6

I get it also, but not nearly as bad, and once I have stopped moving the icon, it goes away. If you are using an ATI card then you may just have to deal with it. I think that there is an option that you can enable in the xorg.conf that might fix it, but it renders slower.

thanks for your answer. well, it can get as slow as it wants to, i don't care. but these traces MUST disappear. i use a NVIDIA 6800GT, so, i may not have to stick with it.

solved - removing/commenting the extmod SubSection with the "omit xfree86-dga:
Code:
# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
#    SubSection  "extmod"
#      Option    "omit xfree86-dga"   # don't initialise the DGA extension
#    EndSubSection

Nope, sorry, did that, still there! :)
Also, mine never disappear when stopping to move an icon, only when I drag a window over the stripes.
Are you running karamba or similar apps which refresh the desktop all the time?

mine did not disappear neither after moving the icons. are you using a nvidia or ati card? do you load the dbe module (double buffering extension)?

i just tested it, if i enable the above subsections i do have the stripes/traces again.

what i did too is to not load the dri module - this is mentioned in the nvidia section.

I am using a nvidia card.
dbe was loaded but unloading it did not remove the problem.

I remember that blender used to have a similar problem once when the GeForce FSAA environment vars were set, however I have those set at 0.

Strange.

I use an ATI card with the 8.16.20 (masked ~x86) drivers. I have DRI working fine and do not have any applications which would refresh the desktop.

My trails dissappear as soon as I release the icon. The same thing happens in konqueror. It seems that maybe we are having a realted problem, but I don't think they'll both have the same solution (nothing is ever so simple).

I found this bug at the KDE bugzilla, I think it's at least related to our problem:
