[pygame] pygamefont problem

[vwf <vwf@xxxxxxxxxx>]

Hello,

I have a rather old problem that fails to work after upgrading. The
problem is that font-rendering does not work correctly. The result looks
like the a television that lost horizontal sync.

I think I use old code, but I don't know what is wrong. I include a
small programme that works, but displays incorrectly (it is a Q&D cut
from my real programme). Any suggestions, or a pointer to an example I
can use?

Thanks,
F.
