Comment 25 for bug 405340

This issues still seems to be around on Ubuntu 12.10 - conky would randomly turn its background into some light grey. Most of the time this happens shortly after logging into the desktop, with conky being autostarted through a ~/.config/autostart entry. In very rare occasions though, the grey background returns to "normal" after some time, without any noticeable trigger.

Conky window is configured as:

own_window yes
own_window_type override
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
