Debounce delay, where art thou?
Two of my mice, one G Pro wired, the other G305 wireless started registering double clicks at just around the same time. I've never had this happen with a Logitech gaming mice for the last 10 years that I've been using them. I'm almost certain that either G Hub or the new firmware that I foolishly decided to flash recently is the cause.
I've experienced the exact same thing with two mechanical Cherry MX "gaming" keyboards that I've used in the past. Both claimed to have low latency, and for some reason they decided to gain more than what is possible from simply having the optimal USB polling rate. BAD idea, and after switching to an older design keyboard that uses the exact same switches my problem was solved. So I haven't had a single instance of a a key registering a double click for about 5 years prior to buying those two newer "gaming keyboards" using again the same switches, then after buying a keyboard with an older design that makes no claim about low latency I haven't had the problem for the 2 years since.
This is what happens when the general public learns about debounce delay and starts running the endless tests. No, you can't have less, because there is a certain amount needed for mechanical switches to function properly. I am perfectly willing to accept that I might be wrong, and it's the switches, but if it's not the switches, Logitech please make my mouse sluggish, laggy and whatever else you can think as long as it is functioning right.
