Another clue, bt headphones working fine, but not even with half of the range as before.
As soon as I connect charging cable, mouse movement is smooth again (not plugged to pc). Everything working as usual on ubuntu, no need for cable.
H i, reporting the same issue (propably). Decided to give it a try on a working windows 10 PC, wireless rf mouse started stuttering at the end of installation and continues to do so after first boot and many attempts to fix it.
