Summary Glitchy output using only HDMI on laptop with AMD Mobility Radeon HD 3450/3470
Severity normal
Classification Unclassified
OS Linux (All)
Reporter tderensis@gmail.com
Hardware x86 (IA32)
Status NEW
Version 10.0
Component Drivers/Gallium/r600
Product Mesa 

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.
