Description bozi 2008-08-15 00:20:25 UTC
Version:           2.9.2-1 (using KDE 4.1.0)
Installed from:    Debian testing/unstable Packages
OS:                Linux

yakuake 2.9.2-1 (debian/experimental)

When yakuake height is set to >60% then the scrolling in the 2nd session become strangely.
Its like a window of lines the stays fixed on the screen und only the upper and lower lines will be scrolled.
In the 1st session the effect is only visible with 1 "bad" line in the lower area.
In the 2nd session (or more) the effect ist much bigger and many lines stays fixed.

Reassigning to Konsole as the terminal area is provided by the Konsole KPart component.

bozi: It'd be highly useful if you could provide information about whether or not you make use of the XComposite-based translucency support, and if so, what X.org release and graphics card and driver versions you're using. This sounds like a series of old composite-related nVidia driver bugs or a similar problem to me.

Reassigning? bad idea, but i forgot to say that i tested this in pure konsole and there it works in the right way. Strange, isnt it?
btw: I dont have any composite foo enabled and i have an older ATI gfxchip (radeon mobility 9000).

> Reassigning? bad idea

The terminal area in Yakuake is entirely provided by Konsole rather than Yakuake code, hence the correct BKO product to track this issue under is Konsole. The fact that this issue does not occur in the Konsole main application may be rooted in differences of code or context between it and Konsole's KPart component, which is used by a number of applications throughout KDE. There's no need to be angry over a reassignment, which is merely done to help solve your problem more efficiently by making the relevant developers (Konsole's) aware of it in addition to myself.

Hi Eike,

Just a heads up, there is a known problem with scrolling in Konsole
with Qt 4.4.  In the Konsole
application itself I have only been able to reproduce it when the menu
bar is hidden.

It appears to be a Qt bug related to alien widgets.  If you start Qt
with the QT_USE_NATIVE_WINDOWS
environment variable set to '1' then the problem goes away.   I'll try
and get in touch with the trolls and see
if any of them can have a look at it.

Regards,
Robert.

Can't reproduce it with yakuake-2.8 and KDE-4.7.0

Feel free to reopen  if this still happens in recent version.
