Same problem here, with no effects activated, on a Radeon M6 LY. Anyway I just have 16mb of memory, so I can't activate them. It happens with: 1) Network manager's notification panel in gnome; 2) Task bar, menu and windows' borders in kde.
Obviously, kde is almost unusable, so I've uninstalled kubuntu in favour of ubuntu -- screen corruption and segfaults with radeon m6 ly https://bugs.launchpad.net/bugs/421842 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
