Public bug reported:
After a recent update (not sure which, certain keys are now behaving
oddly. It's as though the typematic rate delay has shortened AND isn't
stopping once the key is released.
Here are two examples to show what I'm talking about:
If I hit Alt+Tab to open the switcher and release the Tab while holding
Alt down, some times nothing happens, sometimes the switcher starts
rapidly cycling across all the icons, just as if I had held both Alt and
Tab down. If I press and hold Alt+Tab and then release Alt, it keeps
cycling through the icons rapidly as well.
That's fairly annoying as it is intermittent and sometimes makes it very
difficult to select an icon in the task switcher, however this next
example is even more frustrating.
The arrow keys seem to lock as well. So for example, I open a document
in any window (I've seen this when looking at log files via Less in a
terminal as well as very long web pages in Chrome, or PDFs in Evince)
frequently, but not always, pressing an arrow key will cause that key to
lock and once again repeat. For example, I hit the down arrow to
navigated the cursor down one line in a doc in LibreOffice. Sometimes
the cursor will move just one line. Many times, however, the cursor will
move down and continue moving down, regardless of whether I am holding
the down arrow key or have released it. I have to hit the up arrow key
to break the sequence.
I've seen this also happen with the left/right arrow keys when moving
forwards or backwards in a line of text.
IN any case, this happened within the last couple of updates, I am just
not sure how long, but some time in the last 2 weeks is when I first
noticed this.

Title:
After recent update, keys appear to "stick" or the key-repeat
threshold is way too short
