Description
As was already explained in haiku-development (see discussion about Terminal clear behaviour from 5 March 2013), Haiku version of top command-line utility is not perfect in information output. The problem is that every teams information snapshot is pushed into Terminal history instead of overwriting it inplace as other OS' top implementations do. The source of problem is Haiku Terminal implementation of the "clear all" command (\E[2J) - it just fill the screen with empty lines pushing old ones in the history. Possible solution can be refactoring Haiku top to use alternate screen buffer technique instead of normal buffer that is used in current top implementation. That is the way other top implementation go.
Fixed in hrev46472 during GCI 2013.
