Scrolling in Linux/Ubuntu is either too slow or too fast

For VM software that costs $100 per year, I'd at least expect the mouse to work. Can we fix this? No matter what I try, my scroll wheel only registers through evtest every N clicks on my MX Master 3. Works fine on VMWare Fusion Pro...which is free.

 

I've completely stopped using Parallels and just moved over to UTM. It works great. VMWare supports Linux better than Parallels, too. There's no reason for anyone to pay $120 per year to use an old kernel, buggy closed-source tools, and broken drivers when there are OSS or free solutions.

 

Good to see nothing has changed in version V26, I'm wondering how many versions I have gone through with this being awful!

If I connect my Apple trackpad by usb to the VM everything works absolutely brilliantly, I can see in the settings that Ubuntu is seeing a trackpad, everything is smooth as anything.

If I go through the VM then Ubuntu sees it as a mouse, the parallels stuff is actually sending button presses for scrolling up, down, left and right which is why we see this awful scrolling.

Anyone at parallels who cares about this, just run xev in a terminal to test it.

Here is what I get scrolling up and down:
