Recently started getting a lot of double letter input when typing.

I started seeing this same kind of behavior from my keyboard last month. Every other key would randomly start repeating (more like 10 each, instead of 2.) Letters, symbols, space, and backspace were all effective. I could usually tell when it was about to happen, bc a ~10s pause would occur while typing. After the pause I'd start seeing the repeated keys.

Primarily i saw this behavior in Manjaro, but nothing in that install since the latest updates, and nothing when booted from fedora.
