The continued-scroll-after-key-release is most likely because the key repeats
happen faster than the LCD gets updated.

The fact that it "works sometimes" is probably because this is not an issue
while "boosted" (CPU runnning at 124MHz) since then the CPU runs fast enough
to update the LCD faster than the key repeat, and if you play music while
doing this it will boost every now and then for audio decoding purposes.

We've discussed several different approaches to solve this, one of course
being to enhance the LCD update function to run faster but another way could
be to increase the low CPU speed used to something like 60MHz.
