The subject says it all; pseudotransparency looks just weird in an environment with real window translucency.

Sounds good. Which distros & versions have Xgl now? |

Mandriva 2007 and SuSE 10.1 at this moment, with more to come. Mandriva even has live CD called Mandriva One with Xgl/AIGLX/Compiz. gnome-terminal and rxvt-unicode have native support for true transparency.

Ubuntu 6.10 (possibly 6.06 too actually...)
Gentoo
Probably most of the major distros have it as an option now as it's been around for quite a while...
The method could probably be copied from the gnome-terminal app. |

Just giving this a bump...
Ubuntu 7.04 is to have composite support installed by default, Mandriva has had composite for a long time. All other main distros can configure composite relatively easily if it's not already done.
I'll post a screenshot of gnome-terminal with translucency set if anyone's interested but can't be bothered to play themselves  |

Looking good. Looks like the only problem left is the background behind the text?
What's the speed like? |

I've fixed the issue with the text background.
The performance is good on my notebook using an Intel 945GM gpu.
At the moment everything is hardcoded. Disable your background image and transparent background/tinting before using the patch, at least on fedora core 6 you'll get a X11 error otherwise.
Anyway here is the patch:

Please give it a try. In the meantime I'll try to make it replace the existing transparent background functionality ...somehow. |

Now it replaces the pseudo transparency with the real one. Still pretty ugly but at least working. |

Hi, I know I'm probably going to be crucified for reviving a close-to-one-month old topic, but how exactly do you apply the patches? I've tried with my limited knowledge, but don't understand how it works. (or a simple .patch file would be nice  ) |

| I just tested it with the newest version of X-Chat, works fine. Should be integrated by default into the release version. |

Anyway to merge this patch and have an "true trans" GUI option if correct additions appear? |
