If that were the case (or any other hardware related problem), I would
either expect exactly the same pixels to be stuck no matter which way
the screen was rotated, or for different, random pixels to be stuck at
different times (unrelated to whether the screen were rotated or not).

The fact that the stuck pixels changed only when the screen was rotated
(and worked ok when a drag operation was in effect) implied that there
was a software fault.

The screen memory is undoubtedly part of the same RAM chip used by the
heap, and not a part of the normal 4MB of internal flash memory.
