Also, i got strange problem with volume control after update. FN+Arrows skips every second click. This commands tell that system see every second click.
I have the same behavior, though I don’t know if this was the case before the update, as I’ve never used the volume buttons on my Librem 15v4 before the update. I do not see the same behavior for brightness control. Evtest only reports every second button press and so does PureOS.

The mute key (which in the same list above) does not have the same behavior. It works every time it is pressed.
