You can see similar "flashes" in some apps if you have a fade-out effect set for closing windows. Closing Thunderbird you see the same kind of white flash as this bug discusses. Closing Chrome you see the client/page area similarly flash to black while the window fades out.
At a guess, it looks like the "flashing" is the result of windows, or sub-windows, being explicitly unmapped by the application before they're destroyed. So I doubt this is actually a bug in the compiz effects, but the apps themselves, including the code that renders indicator menus, need to be made to not unmap their windows if they're being destroyed anyway. That might stop this problem from occurring. Just a theory. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/687567 Title: Global menu causes white "flashes" when scrubbing/moving with mouse fast over menus To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/687567/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
