Public bug reported:
when i login, the graphics appear to change modes to a higher
resolution; the login screen becomes smaller and random images and noise
show on the right and bottom few inches of the screen. when the desktop
is done loading, the graphics work fine.
i would expect to see a beautiful transition upon logging in. the
garbage displayed make the OS look bad and can also reveal portions of
previously running programs, which is bad for security.
i am using an nvidia hybrid graphics card with the proprietary driver.
