Version: (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages Sorry for my poor english. I have bug when I open Console and type Help. I see information correctly, but when I move mouse wheel, some lines not showing, but I see couple clones of another line. It is hard to explaine, I try to attache screenshots. Bug is unstable, I see it 1 time of 4-5.

You are referring to the history? If you scroll up with mouse or arrows, the text is not correct?
Hello, can you try the following from a terminal: export QT_USE_NATIVE_WINDOWS=1 konsole And see if the problem occurs in the new window that appears.
# "You are referring to the history?" I guess yes. "Help" command place to much text and I try to scroll up to see the beginning of text. # "If you scroll up with mouse or arrows, the text is not correct?" Exactly. Only if scroll up. By mouse wheel or scrollbar arrow or by moving scrollbar slider. And when I select text by mouse, bug in selected lines vanish. Right now I see that I have similar problem with "Add widget" window, but only when use "arrow up" from vertical scrollbar (with mouse wheel and "arrow down" all is correct). When I move mouse over widget list, bug vanish. Some application is OK: Shiretoko browser is OK. KPackageKit is OK. So, I found this problem only with "Konsole" and "Add widget" right now. I don't found "terminal" (where is it? I use Kubuntu) and type next commands in konsole: ~$ export QT_USE_NATIVE_WINDOWS=1 ~$ konsole konsole(4533): Attempt to use QAction "change-profile" with KXMLGUIFactory! No effect. Some time one of my konsoles work correctly, but right now all my 4 konsole windows working with this bug.

Does this problem still happen in recent version?
Sorry, but I can't reproduce bug, because right now I don't have installed linux.
Can't reproduce it in KDE-4.7.0
