           Summary: Vim scroll speed is slow and jerky in Konsole.
           Product: konsole
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: mindentropy at gmail.com


Version:           unspecified (using KDE 4.6.2) 
OS:                Linux

A medium(606 lines) to long file scroll is very slow and jerky in Vim. The cpu
utilization is also quite high. General scroll speed in a console application
in Konsole is slow.
The expected behavior should be similar to xterm. Vim scroll speed in xterm is
very nice and its a pleasure to program in it.

Reproducible: Always

Steps to Reproduce:
Open a file which has ~1000 lines.
Scroll up and down to notice the behavior.
You can check the CPU utilization jump abnormally when scrolling.

Actual Results:  
The scroll is jerky and slow.

Expected Results:  
The scroll should be smooth similar to the behavior of xterm.
