Transparent images with ARGB visual enabled

Output of conky -v

Yes, I confirm this problem with version 1.8.1. Conky use with compiz in Arch.

It appears to be (mistakenly) using values from the background image to apply transparency to the $images. Against a white region of background the images are completely transparent. $images over darker regions are partially-transparent, and over a black region it's properly opaque. Obviously the images should be opaque regardless of the background image.

It also affects the colours of the various graphs.

This problem is still present in Conky 1.9.0 on Ubuntu 13.04.

Same issue with 1.9.0 on current Arch Linux.

This is being caused by blending being enabled when imlib2 renders to the drawable, which makes sense when using fake transparency but not for argb visuals.

Attached is a patch that disables it when own_window_argb_visual is enabled, while leaving it enabled if fake transparency is in use. This fixes the problem for me.

I've also attached a screenshot showing 2 ARGB conky windows overlaying each other without the image wash-out and partial transparency.

I'm not sure how active conky development is with the last release being 3 years ago, so I'll give this a little while but if I don't hear from anyone I'll see about getting this included as a patch in some distribution's packages instead.

I'd like to hear feedback from others testing this as well.

This patch is now included in the official conky package in Arch Linux as of version 1.9.0-5. I'll try to get it included for the Debian package next.

Thanks Brenden, that github isn't too obvious with sourceforge coming up at the top of search results - is there any way to close this sourceforge project and redirect to the new github one?

It looks like a fair amount has changed since the last release and the current github code, I'll rework the patch for it.
