<pre>Still present (exactly as in the video) with kernel 3.8.0
libdrm and libkms 2.4.42 + git shapshot 13/02/25 commit 41fc2c...
mesa 9.2 + git snapshot 13/02/25 commit 533dc3...
xserver intel driver 2.21.3 + git snapshot 13/02/25 commit 421910...
I have discovered that I encounter a similarly looking rendering issue, with
the image getting decomposed in multiple pieces that are not correctly aligned,
on the whole screen whenever I attach an external displayport monitor and call
xrandr --output DP1 --auto --primary --output LVDS1 --off
curiosly, this does not happen if I first switch on the monitor and then switch
off the laptop screen with 2 independent xrandr calls.</pre>
