Description Scott Glaser 2008-03-24 20:31:12 EDT
Description of problem:

With compiz installed and desktop graphics enabled Xchat hangs and puts an
extreme load on my duo-core 1.6ghz laptop.  


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

compiz-gnome-0.6.2-3.fc8
libcompizconfig-0.6.0-3.fc8
compiz-fusion-extras-gnome-0.6.0-1.fc8
gnome-compiz-manager-0.10.4-3.fc8
compiz-fusion-extras-0.6.0-1.fc8
compiz-fusion-gnome-0.6.0-12.fc8
compiz-0.6.2-3.fc8
compizconfig-python-0.6.0.1-2.fc8
compiz-manager-0.6.0-4.fc8
compiz-fusion-0.6.0-12.fc8
xchat-2.8.4-11.fc8

How reproducible:

Occurs with each and every login with desktop effects enabled


Steps to Reproduce:

1.  With desktop effects enabled at login open Xchat.
2.  System load increases exponentially and Xchat is extremely slow. 


Actual results:

System load increases exponentially and Xchat is extremely slow. 

Expected results:

If desktop effects are disabled Xchat runs normally and does not produce any
system load. Once Xchat is running desktop effects can be enabled and Xchat will
run normally.  This issue is only apparent if desktop effects are enabled when
starting Xchat

Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

This can not be accomplished as this is an nVidia Corporation GeForce 8600M GS
(rev a1), so removing the xorg.conf and allowing the system to recreate it will
not work.  In order to utilize compiz I need to use the kmod-nvidia and
currently autodetect will not pick up on the nvidia driver it will default to
the nv driver which will not allow for desktop effects to be enabled.  

I did also notice it is not just Xchat that is impacted, it is everything from
Firefox to Evolution that show these same symptoms.  As I stated above the
symptoms are present if desktop effects are enabled at login time.  If I disable
the desktop effects and then re-enable them after logging in the symptoms go away.

Let me know if you would like me to try anything else.

Xchat has a very stupid redraw implementation.  We hit the same problem with
Xchat and compiz for the open source drivers and was able to work around it to
some extent in the drivers.  We can't fix this for the closed source nvidia
driver.  I suggest you report the problem in nvidias bug tracker.  Thanks.
