A single pane goes entirely black for a few seconds then comes back on. I don't
see any discoloration or tearing or any other visual artifacts.

I'll watch for any correlation between pointer and screens
<span class="quote">> Is there any chance you can record the flicker using a phone?</span >
I'll see what I can do to get this for you.

Any screencast apps that you recommend I try? Or just anything?</pre>
