           Summary: Artefacts in kicker and konsole: colourful scrambled
                    garbage
           Product: kde
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: Marco at NightLabs.de


Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    Ubuntu Packages

Quite often, already for quite a while (with KDE 4.1 as well as KDE 4.2), I
have bad artefacts in kicker and konsole as well as the main desktop
background.

Take a look at the screenshots I attached to this issue:


*** kde4-artefacts-kicker-screenshot.jpg ***
This shows how kicker looks like quite often: It is impossible to know where to
click, because the whole kicker area shows only scrambled colourful garbage.
Note that it's fully functional - only a display bug.


*** kde4-artefacts-konsole-screenshot.jpg ***
The right side is a konsole window (even though it doesn't look like one). You
see that the Eclipse window is shining through and the scrambled konsole shows
some real console contents only in the lower part.


For the artefacts of the background, I have no screen shots, because it was not
yet annoying enough ;-) It's only colour inversion of my background images or
the background images stay completely black. The dashboard-widgets on top work
fine.


I have the impression that all these problems mainly occur when I'm using a big
application window that covers both of my monitors (I'm using big-desktop with
an Nvidia GeForce 7300 GT). If I have only small application windows (that
reside on only one of the monitors) the problem seems to happen only quite
rarely (or even not at all). It's hard to say for me, though, because I'm
working most of the time with big application windows (=> Eclipse).
