| Summary | Glitchy output using only HDMI on laptop with AMD Mobility Radeon HD 3450/3470 |

Screen flickering and horizontal black/white lines mixed in with output on redraw. This only happens when using HDMI output to a single external 1920x1080 monitor and not when using dual monitors or the single laptop screen. If the screen is static or I move the mouse over a single color background, no glitching happens. It seems that the more that needs to get redrawn in the frame, the worse it gets. I'm not sure how long this has been a problem because I rarely use a single monitor. I'll report back when mesa 10.1 is released on Arch.
