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.

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.

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

Comment on attachment 38854 [details] Inject -graphicssystem raster into argv I believe this patch is on the wrong bug.
Have you noticed this issue with a recent version? 4.5.x or 4.6.x? Reopen if you can with steps to reproduce.
