my konsole acts weird when using the fixed width font Anonymous Pro. Specifically, the width of characters seems to vibrate.
See video ( http://static.cowsandmilk.net/videos/konsole_font.ogv or http://static.cowsandmilk.net/videos/konsole_font.mp4 ) and watch the width of the third line change as my cursor goes back and forth.
This is openSUSE 11.2. I can provide any other details needed.
