Description Axel Roebel 2008-08-06 12:05:23 UTC

Version:           2.1 (using 4.1.00 (KDE 4.0.99 (4.1 RC1+)), 4.0.99-1.fc9 Fedora)
Compiler:          gcc
OS:                Linux (i686) release 2.6.25.11-97_1.cubbi_tuxonice.fc9.i686

Scrolling with mouse wheel or scrollbar works fine if menubar is visible.
If menubar is invisible there are very often lines that do not update correctly, disappear or reappear. See the screenshot for an example
of a display that changed after scrolling down by one step.

Comment 3 Axel Roebel 2008-08-06 12:34:48 UTC

Hi again,

it seems I can avoid the bug if I scale the window down to about 20 lines.
I can reproduce it with size 145x32 on fedora 9 Version 4.1.00 (KDE 4.0.99 (4.1 RC1+) as well as on Version 2.1
Using KDE 4.1.60 (KDE 4.1.60 (KDE 4.2 >= 20080709))
which I compiled from source using kdesvn-build.

After having a look again on the 2 attachments I found that I stored the same screenshot twice. So I now tried to reproduce it and had some problems with that. Everything worked fine until I resized the window  while a svn status
command was running. I created new screenshots for the problem.

scrolled down by one line

Note that the strange output disappears after enabling menubar display

Comment 6 Kurt Hindenburg 2008-08-10 21:52:39 UTC

Confirmed in trunk; seems to be an issue with the height of the menubar when it is hidden.

Inject -graphicssystem raster into argv

My temporarily workaround to get konsole working by injecting the arguments -graphicssystem raster into argv.

I believe this patch is on the wrong bug.

Comment 10 Kurt Hindenburg 2011-04-24 06:49:19 UTC

Have you noticed this issue with a recent version?  4.5.x or 4.6.x?

Reopen if you can with steps to reproduce.
