Pixelperfect conky theme

Thanks for sharing, this is the only conky I've come across in a long while that I actually feel like running on my system.
But I have a problem - running on Ubuntu with Unity and Nautilus handling the desktop, I get blurring and distortion of fonts when using the "override" setting for own_window. If I use "dock" it doesn't seem to happen, but then the global menubar does not function properly.
Is there anything I can do in the conky rc itself to make sure the fonts render properly? I googled, but turned up nothing so far.
Btw the blurring seems to be triggered when I launch some apps, like image viewer, background chooser, etc.
Thanks.
