This really does sound as if it might be related to the bug I reported
in the middle of this thread.  My bug relates to the trackpad and only
started with 15.10.

Occasionally the cursor gets stuck on one mode and affects only one
window even though it can be moved all over the screen.  If, for
example, this happens in a terminal window the cursor is a text cursor
wherever you move it on the screen and the trackpad middle button
always pastes in the same terminal window wherever the cursor is.

If you turn the trackpad off the fault goes away (but you have no
middle button).  The fault also clears if you switch to a console
(CTRL/ALT/n) and back to the X GUI which is a reasonable workaround
for now.

I'm pretty convinced the bug is something to do with the X handling of
keyoard and mouse.

It's as if something doesn't reset/return in the code such that in
your case the auto-repeat doesn't stop and in my case the cursor
doesn't change when moving about the screen.
