In my asklemmy post (here: https://lemmy.world/post/20013379) I asked if anybody could help me because the mouse just does not glide well on my mousepad, while the 10 year old gaming mouse does glide.
The answers were pretty good and something I looked into. Then, I was just like “what if…” and put regular tape on the mouse, just to test it… and… it glides!
The edges of those slider bits can be pretty rough from the factory. If you want to skip the tape just slightly sand or file the corners of the mouse. Once they wear they get a bit smoother, but some gamer mice have some insane anti grip pads that have 0 traction, but the Apple ones have a bit even once worn in.
