--- Comment #26 from Jason <[email protected]> ---
Im not going to reopen this, but I don't believe it is fixed. I believe I was
too hasty in assuming that it was. It does seem that something has changed, but
I don't have enough knowledge to say exactly what it is.

First, I have a Razer Viper V3 Pro, and a Pulsar xlite v3- both exhibit the
same behavior. If I turn the scroll speed down in KDE, even the workspace
switcher swallows keystrokes. If I turn it all the way to minimum scroll speed,
it will take many scroll clicks before the switcher changes workspaces.

Leaving it at default, this doesn't occur. However, it seems that virt-manager
at least registers three scroll events for every single scroll event. I've
confirmed this with libinput- you can see the 3 15/120 events occurring at the
same time for each click. When you change directions (scroll up instead of down
for example), the first will give only 2 scroll events, and then 3 scroll
events over and over. Basically, the guest will act as if its receiving 3 down
clicks.

This differs from before. Before when I would scroll, I would get 1 event, then
2 events, then 1 event, then 2 events, etc. This would result in uneven
scrolling per click (3 lines -> 6 lines -> 3 lines -> 6 lines, etc). Now it
seems as if it is doing 3 events, 3 events, 3 events, etc and thus the scroll
speed in the VM seems very high. I've tried everything.

Using the same virt-manager (on Fedora Workstation) with the exact same guest
VM (up-to-date Arch) 'sudo libinput debug-events', I get 1 event per click
(instead of 3). If noone comments here, I will open another bug report.
