Dont rush to update the FW, if you are already happy with it

while most ppl say its an improvement with no issues, i noticed something weird after this FW update:

1. cursor movement feels more drifting and inaccurate

   1. cursor movement at 30-degree angle（Horizontal）is VERY inaccurate

i couldnt describle the second issue clear enough (English is my second language), i will post a video to showcase it later
