Sometimes, the mouse scrolling speed changes to a very slow rate, where it takes many clicks (3-8 clicks) or significant wheel rotation to scroll the page one step. This started after upgrading to linux kernel 5.0. It has not happened yet after booting back into kernel 4.20.
When it happens, it's usually upon the wireless mouse 'waking up' after having gone into its power saving mode, but it does not happen every time.
Turning the mouse off and on again with its power switch restores normal behavior.
The mouse is a wireless Logitech M720 used with a Unifying receiver. There is also a wireless keyboard, a Logitech k830, paired with the same receiver.
I know kernel 5.0 introduced new high resolution scrolling support. Is this a bug with that feature? Has anyone else experienced this?
