ugly default font in plots (x.org configuration problem?)

Bug Description

The default font in the plots of R is badly rendered or scaled. A partial workaround is to specify a family of fonts, however, the rendering is still not as good as it should be.

I think this is a problem with the default configuration of X.org since other applications show also ugly fonts.

Much better although the "3" in the y-axis is still badly rendered.

Obtained with:

I noticed that the font used by xfontsel is strange. Any ideas? Some relation? Different bug?

Installing xfs (X font server) fixed the font issues for R. However, the font of xfontsel is still weird.

This works fine for me on an up-to-date Dapper install. Can you please confirm this? Thank you.

Tried the 3 R commands in the initial post and attached the boxplot. Looks fine with me (on Breezy, no specific font configurations set).

Hi Marcus, do you have xfs installed?

Anyway, it must be some configuration problem or conflict between packages that only shows up if a particular combination of packages are installed. I had many problems with the fonts in xmms, R, xfontsel and other programs. xfontsel still looks weird...

I would report again after upgrading to Dapper.

Lowering Severity and Priority since it seems that not many people are experimenting this problem. I will close the bug if I cannot reproduce it in Dapper (and nobody else reports it either).

Works in Dapper. I am going to close the bug report now. Since nobody else experimented the issue, I guess it was some problem with my fonts configuration, so closing as rejected.

I also have this problem in R (using Gutsy). The strange thing however is that par(family="symbol") produces some good-looking plots without rendering problems.
