Description Andrew Farris 2008-03-05 21:38:11 UTC
Description of problem: The gnome-system-monitor resources tab has 3 horizontal graphs. On my system for awhile now I've had this tab cause 100% cpu usage (by gnome-system-monitor) and the graphs are terribly misshapen, blurred, and replicated (see screenshot). I believe there was some discussion on this (I remember posting this screenshot) but cannot find where it was (may have been an upstream bug, something about the new graph style and image rendering?). Version-Release number of selected component (if applicable): gnome-system-monitor-2.21.92-1.fc9.i386 How reproducible: Every time it is opened. Steps to Reproduce: 1. Actual results: view resources tab, wait for a few seconds to see graphs update incorrectly Expected results: view resources tab, see clear, unblurred graphs

I found the discussion: https://www.redhat.com/archives/fedora-test-list/2008-February/msg00366.html And upstream bug mentioned there: http://bugzilla.gnome.org/show_bug.cgi?id=328101

Created attachment 297681 [details] rawhide-testing/Screenshot.png Screenshot of this issue, graphs being drawn incorrectly.

Is this about "100% cpu usage" or about "unclear/blurred graphs"?
Comment 5 Andrew Farris 2008-03-14 20:48:59 UTC
They are (as far as available info so far indicates) related issues. The upstream bug has discussion on CPU usage for drawing the graphs as well as issues of the rendering done incorrectly. I think part of the problem was that the patches that introduced the new graph drawing style caused huge cpu load because too many data points were used when the graphs were not very high? Anyway, both things occur at once right now. The high CPU load usually stops after a short period but the graphs remain messed up. If you change tabs to the process list and then back to the resources graphs the CPU load will return for awhile and then stop, and the graphs are still messed up. I'm willing to work on this but not really sure how to try and figure out how these are related problems.

Appears to be fixed in gnome-system-monitor-2.22.0-1.fc9.i386. Both high load and blurry graph drawing.
