Hi, thank you for your support. I tried on a older PC also (P4-based Celeron 2.0 GHz + integrated i845 graphics) and the problem is much more pronounced: moving a window over another one cause the bottom window to be almost fully greyed. Removing the "inset" text-rendering propriety significantly reduce the problem, and using a simpler theme (eg: Clearlooks, Mist, etc.) result in a even less pronounced gray trail (and lower CPU usage).
Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/878958 Title: Default theme "Lubuntu-default" is too much CPU intensive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lubuntu-artwork/+bug/878958/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
