My fucking mouse is dogshit dude. I think I actually need to get a new one. Left click doesn't stay held down. I don't think this is a switch issue though because it's really inconsistent. It'll work fine for a stretch of like a week but then there will be 3 hours where it's just dogshit.
I've seen some people saying it could be an issue with the voltage regulation or something along those lines. An actual fix is to leave the mouse turned on without a battery inside of it overnight. Like how tf did Logitech screw that up?
It doesn't help that everyone makes it fucking impossible to take a mouse apart. Yeah, rip off the feet of the mouse so it gets permanently damaged just so you can clean it. Real fucking cool.
And to further this theory, it also occasionally happens to right mouse click. Very rarely, my side mouse buttons stop responding for like 30-60s. Maybe it's because I'm using cheap batteries or something? I don't have any other batteries to test.
