Description of Problem:

When viewing email in Evolution XFS uses 100% CPU utilization and there is as
much as a twenty second delay before the email is displayed.

Version-Release number of selected component (if applicable):

Evolution 1.0.8  
Stock RH 8.0 XFS, couldn't find a version, maybe it's Xft 2.0-1 calling itself xfs?

How Reproducible:

At will and on demand.  Seems to depend on the email. A simple text email
doesn't seem to have a problem, but a complex email with fonts and colors takes
a long time

Steps to Reproduce:
1. open any font/color rich email in Evolution

Actual Results:

Expected Results:

Additional Information:
I can send an example email if needed, but almost any will do.

xfs is the X font server. Xft is a library for doing fonts without
having to talk to the X server or X font server.

Most likely this is an evolution issue of it asking xfs to do
a lot of work.
Comment 2 alan 2002-10-04 19:45:58 EDT
I installed the MS Web fonts package trutype fonts in ~/.fonts/ and the "lag"
went to less than a second and CPU utilzation stayed low.  A huge difference
from 20 seconds and 100% utilization.  Looks like Evolution was making XFS look
for fonts that didn't exist then timing out or something.  Anyway, the web
truetype fonts in ~/.fonts/ seems to make the problem go away.
Comment 3 Jeremy Katz 2002-10-05 10:29:52 EDT
It's actually probably just picking fonts which X renders slowly.  This is not
an evolution bug at least.  If you'd like to follow up further on it, please
file a bug against XFree86.
