Looking at metacity's change history, I see that 16-capture-before- unmap.patch was introduced for Unity2D, but caused bug #740387. A gconf option "capture-before-unmap" was added but this was left on by default. In metacity version 1:2.30.3-0ubuntu8 it was switched back off by default, but those who upgraded during the period that it was on would have seen it left on, and thus the corruption would remain.
So, it would make sense that anyone seeing corruption similar to what's described in this bug, check your gconf setting for the key: apps/metacity/general/capture-before-unmap If that is ticked 'on' and you're seeing corruption, switch it off (and maybe restart?) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/654768 Title: compositor produces artefacts starting in maverick To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/654768/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
