I was able to reproduce the corruption with /apps/metacity/general/capture_before_unmap set to false which rules out this patch being the problem.
I tested on natty using with nvidia graphics and natty beta and latest from unity-2d dpaily ppa. See attached video. This is how I am able to reproduce reliably: 1) make sure you have files on your desktop (not sure if this is required) 2) open two terminals and have them overlap 3) show dash using Super key 4) hide dash using Super key 5) show applications place by clicking on launcher 6) hide it pressing Super key 7) show dash pressing Super key bang, the windows that were beneath the apps place are corrupted -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/740387 Title: graphical corruption with multiple drivers and classic desktop -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
