Also check Bug 1308069 for further reference.
I did a quick try with, but I didn't see the blurred squares on my Nightly.

From the video, the first time we saw blurred squares, the blurred squares seem disappeared after few milliseconds? I don't know if the second one is the same, the video doesn't record that.

Do the blurred squares disappeared if we stay the same position and wait a bit? Or they just stay blurred unless we zoom out and zoom in again?

Hi Edgar,

Be sure to try it out on Windows 7, it can't be reproduced on any other OS.

The squares disappear if I move over to a different location or change the zoom level. Otherwise, they will remain displayed until further action.
