 == Issue ==
 When switching from landscape to portrait, or from portrait to landscape,
 the screen temporarily shows a distorted image.  Chances are the
 orientation swap happens slightly before/after the change to the video
 buffer.  (Portrait to inverted portrait, or landscape to inverted
 landscape does not have the same problem)

 Perhaps the screen should be blacked out (or some other uniform color) or
 the backlight should be temporarily shut off during the orientation swap.

 == Reproducing ==
 1) Install the accelerometer gestures and screen orientation software as
 instructed here: Or use the xrandr
 command to change screen orientation manually.
 2) Rotate the orientation of the display.

 == Software ==
 * Latest update from unstable feed
 * opkg list_installed attached
