I have of course seen the account related issues reported after the downtime, but on the brief window that the worlds were open, I started to have graphical issues. Whenever I zoom in and out in the character selection screen, or whenever my character is running, all of the background becomes black pixels, which are then restored when I stay stationary. So it seems like there is a problem with motion of the background.

Since I never saw anyone reporting graphics issues, I am wondering did it happen to anyone else? And how to fix it? This was not happening at all before the maintenance.
