Hey, I can at least let you know you are not alone.
When my G602 wakes up, it presses random buttons. Sometimes that's just a simple click, left or right. Sometimes it changes DPI settings one notch. Worse however is when it wakes up and triggers the Paste shortcut. Had a bunch of cases where it pastes whatever is in the clipboard into an open IDE window... always great to have youtube links in your code.
I suspect the crapware that is GHUB. It's done a number on my mouse, like no longer being able to change the hardware stored profiles and other nonsense.
