Does the flashing pattern change, when you move the mouse?
If so I know the reason.

When changing resolutions, X intel driver doesn't hide the cursor, and
thus if you change to lower resolution, cursor might be placed outside
the screen, and this confuses the output pipes. (and I didn't find a way
to fix this, but a reboot)

I have committed a patch to fix that in intel driver, about year ago,
but with kernel modesetting it is back, and I don't yet have time to fix
it.
