           Summary: Very laggy konsole when lots is outputed
           Product: konsole
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: simon at esoft.dk


Version:            (using KDE KDE 3.1.2)
Installed from:    Gentoo Packages
OS:          Linux

My konsole seems to lag extremely when most of the console area is filled with characters. I'm using Gentoo Linux, but this same behaviour was found when using Slackware too. I'm running at 1600x1200 resolution with a fullscreen Konsole, so it's quite a large amount of characters (157x52).

The lag is so extreme that changing to another konsole (in the same tab-window) takes forever and mouse events seems to be lost I have to click about 10 times at the tab to get it to change. Sometimes it can even seem to freeze my XServer for seconds at a time. Also the Konsole is generating a large amount of CPU load by itself

My suspicion is that the font is causing this problem, however I've tried every font available in Konsole, and all lags. An xterm however does _not_ lag.

To reproduce, I just do a "find" from the root.
