I set a background color for xfce4-notes using the custom option and the color picker. The color changes as expected and xfce4-notes continues to function normally.

After system restart xfce4-notes process uses 100% CPU and the notes icon does not appear on the panel.

Comments from the Xfce notes developer:

Please attach your configuration file:

$ cat ~/.config/xfce4/xfce4-notes.gtkrc
$ xfconf-query -c xfce4-panel -p /plugins/notes -lv

I was never able to reproduce such a bug :(

Can you try to install version 1.7.7 and see if it reproduces?

Comments from Xubuntu - version 1.7.7 is not yet available in Natty.

An additional comment: If I kill the offending xfce4-notes process, and then restart by selecting Notes on the xfce4 menu the excessive CPU usage does not resume.

I'm not having much luck with installing xfce4-notes-plugin-1.7.7.
The gtk+-2.0 dependency is a bit of a hangup.

Sorry, I cannot help further.

I believe having reproduced the bug, actually, but it doesn't reproduce easily.
It seems to be a race condition, it can be both in GTK+ and the notes plugin.
The cause can certainly be the theme, since GTK+ and theming are two things
that don't fit well, but I can't change anything about this.

The solution is to simply stop / restart the plugin.
