I’m surprised people are only noticing this on Big Sur, since I’ve been seeing this as early as Mojave using a 1kHz ‘gaming’ mouse. (It may have happened in even earlier versions of the OS and is just getting progressively worse on every new macOS release…)
I suspect this is at least part of the reason why some people have mysterious performance problems with VirtualBox on macOS[0]—at least, it’s how I first noticed the problem. (I’m sure VirtualBox has some other issue going on too, since its event queue gets backed up so badly that even keyboard events become delayed. Life gets interesting when the delays are so long that the guest OS key repeat is triggered!)
Does anyone know of some small utility that adjusts mouse polling rates to at least mitigate the issue? The official Logitech software to do this is 476MB, 5 kernel extensions, and a launch daemon, which is a bit much just to send a USB command.
What if you used something like Synergy so that the mouse and keyboard input is shared over networking between host and guest rather than the virtual USB interface?
