Must be you for mouse slips?
That was the first thing that I was considering, but the point is that this is not happening on different sites. I think that something is glitching - don't know what though.
I agree on the mouse, touchpad slips issue. Playing here doesn't feel smooth and pleasurable. In addition, the board is too small and the tips to resize it are also unacceptable. All in all, the playing experience here just isn't fun for me. This is not a compliant or trolling. I hope this is read as constructive criticism.
Don't know what to do. Changed my mouse but its still happening. Especially here. I am constantly slipping and that cost me many games especially in bullet, and what is even more outrageous in rapid. It's like my left click was not working properly. Any solutions ? I changed my mouse drivers already. Thanks in advance.
