Please describe the problem:
The Screen is not cleared correctly after changing a windows size.

This bug is really unnerving when using gnome-terminal with a specific pattern.

Steps to reproduce:
1. 
2. 
3. 


Steps to reproduce: 
- Open new terminal
- ls -l /usr/bin
- Maximize Terminal Window with window manager's maximize facility 
- ls -l /usr/bin | less
- De-Maximize Window
- Exit less (by using the "q" command)


I use Terminal with this pattern _a lot_ , and so this really annoys the heck
out of me.. :-/
I would be greatful for a quick fix.

Actual results:
This reproducibly leads to junk being displayed on the line next to the command
prompt! 

Expected results:
Screen being cleared normally, no annoying junk right of the command prompt.

Does this happen every time?
Yes

Other information:
How can it be this bug has not been filed yet? It's really unnerving and has been existing for several years!
