Description of problem:

Konsole does not render text properly when using other than the (default) Monospace font. The bottom part of the letters is cut-off. The attached screenshot shows how do the letters 'qpo' look like when I select the Terminus font. The underlined text is not rendered properly as well.

The default Monospace font seems to be OK.

Steps to Reproduce:
1. Run Konsole
2. Go into 'Setting -> Configure current profile -> Appearance'
3. Select other font than Monospace (such as Terminus or Inconsolata)
  
Actual results:

Bottom part of text does not render properly: characters such as 'q', 'p' have cut-off their bottom parts.

Expected results:

All fonts render correctly.
