I have the pro version. The mouse is wired. I have tried unplugging it and then plugging it back in. I'm running on an AMD Ryzen 3750 based machine with 16GB memory.
I have enabled 200 percent scaling on my 4k monitor. I also tried altering the font sizes. I set them all back to what the system defaults were but the problem persists.
I tried connecting a Bluetooth mouse. The problem seemed to momentarily go away. Then it came back. If I turn off animations, both mice track in a very chunky mode and are practically useless.
I'm at the stage where I can just go back and rebuild the system. I do have a backup. I just wanted to see if there was an easy solution. I also really want to participate in some small way.
I'm really liking this OS and GUI. I sacrificed Windows on a brand new machine to run it. Even with this little snafu, I'm not missing the Windows.
