Mouse sensitivity bug?

[Malric is a dude]

Sometimes when I’m in a fight my mouse gets some kind of sensitivity-spasm, the mouse speed suddenly shoots through the roof and I get really disoriented. This is a problem I had in C:MW too. Seems to happen mostly when I’m using smaller secondary weapons right after someone parries or blocks my attack.

Is anyone else having this problem? Maybe It’s my mouse giving up.
