SUMMARY

Slight UX woe within KSystemLog. Scrolling does not stay stable when I set "Scroll to new lines" off - log lines keep crawling up.
I see this as the middle ground between the default following mode and stopping watching logs altogether. As such, screen content should not change.

STEPS TO REPRODUCE
1. Start KSystemLog, observe new log lines pushing up old ones (=following new logs)
2. Right-click, set "Scroll to new lines" off

OBSERVED RESULT

Log lines still keep moving up at the pace of incoming new logs. 

EXPECTED RESULT
Stable screen: log lines only move when user scrolls away. New lines get appended to the bottom (as if just growing downwards).
