Light blue or light green streaks, sometimes in patterns, sometimes somewhat random. I also began getting environment lockups (especially during flash video play) with messages in the syslog like: Oct 19 20:03:27 hosanna kernel: [130892.932466] NVRM: Xid (0000:01:00): 8, Channel 00000001 Oct 19 20:03:43 hosanna kernel: [130908.918695] NVRM: Xid (0000:01:00): 8, Channel 00000001 By environment lockups, I mean the video would stop, and I couldn't click on any windows, or use the keyboard, but I could still move the mouse around. This behavior did not start until after I did a sleep and wake up after the upgrade. I forced a downgrade, slept the laptop, woke up, and so far I can play flash video without lockups, and have yet to see any visual artifacts. $ lsb_release -a No LSB modules are available.
