It is basically drawn line by line, but sometime as line-part by line-part. 
This happens when parts of a line have e.g. a different color. I assume that 
konsole should just draw the characters "as-is" and should not try to do any 
right-to-left logic? 

The actual painting happens in TEWidget::drawAttrStr() btw.

Does the following patch fix the problem?
