With the new driver, I've started to get more of something similar – different colored dots. Before this driver version there wasn't a lot of them (a few in the boot loading stage), but now there's almost 20 (?!) of them boot time and they even appear in the desktop sometimes.
A clipped screenshot is attached (x-bug-green-dot.png – "Green dot"). If you think this is a completely different bug, I'm happy to report a new bug, but from my point of view these two things are really closely attached and they always appear together. ** Attachment added: "Green dot" http://launchpadlibrarian.net/28596202/x-bug-green-dot.png -- Black areas appear on the screen randomly https://bugs.launchpad.net/bugs/361568 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
