I'm now running kernel 5.10 on Debian. I finally got tired of it enough a few months ago and replaced the keyboard and all of my issues resolved. There are enough people reporting the problem here that it may seem this is a common failure mode for this keyboard.

The touchpad has three "mouse" buttons on top, and none of these buttons currently function. Using xev does not show any output from these buttons. The touchpad itself works fine. There are two bottom buttons integrated with the touchpad, which do not work consistantly. The left button will sometimes act like a left-click and sometime like a right click, making it hard to move applications on the screen. The right button acts like a left click and only sometimes bring up menus. Trying to change from a left hand to a right hand mouse in mouse options does not change the behavior.
