Description Ivan Ochagov 2011-04-24 15:49:16 UTC

Version:           2.9.7 (using KDE 4.4.5) 
OS:                Linux

When I try to scroll back using scrollbar or 'less' program duplicate lines of text appear instead of normal text. Scrolling forward is OK though.

Reproducible: Always

Steps to Reproduce:
1. Fill the scrolling buffer with some output so as you'll be able to scroll backwards
2. Scroll back with scrollbar or mouse wheel

Actual Results:  
Duplicate lines have appeared

Expected Results:  
Text from the buffer should have appeared

OS: Linux (i686) release 2.6.32-5-686
Compiler: cc

Reassigning to Konsole as terminal painting is done by the Konsole KPart component.

This is likely to be a bug in your graphics driver however. Try starting with --graphicssystem raster.
