Describe the bug Solaar reports that the mouse is operating at 125HZ polling rate, the mouse was set to 1000HZ on windows and polling rate checker from Benq reports 1000HZ (tested on OpenSUSE). I might not understand something or the value is wrong.

Additional context I have a few questions that I was hoping to get an answer, I hope it's not a crime to do it here:

1. What is high-resolution scrolling? the option is available in Solaar on M345 and M235. I did test it but I don't understand how it works, because it feels like increased scroll sensitivity but it probably is much more than that.
2. does g305 not include high sensitivity scrolling feature? (it's not present in Solaar)
3. why serial number presented in Solaar is different than the one on the mouse's label
4. I paired each m345 and m235 with nano receiver, and both of them has not encrypted connection, is it normal or its receiver mismatch.
5. I am very grateful that you created such a beautiful tool for Linux users, Thank you!
