Several years ago, a coworker made an Arduino "mouse" that traced a square with a 1KHz report rate. Multiple systems running Windows 10 and reading mouse updates via either regular window events or the Win32 raw mouse API would occasionally lose events, meaning the square would drift over time. We tried both with a custom app and with drawing programs like Paint.

We could not reproduce the issue on systems running macOS or Linux, and we chalked it up to a bug in Windows. It was hard to know if it affected real mice but I expect it did. I haven’t tried retesting with more recent versions of Windows to see if it is fixed, maybe it has been.

Anyway, I’m not disputing OPs claim, I can totally believe it, but I always thought it was funny that pro gamers on Windows with high end mice could be losing the occasional movement and apparently nobody noticed that.
