Mouse sensitivity issue
So ever since Monday, I've noticed my mouse sensitivity go to almost 0 randomly during the games. It's especially bad with laggy servers, which didn't used to happen on laggy servers, but it seems to happen during rather normal moments too. Not a hardware issue since I have no problems playing other games or in other general use. Also I've noticed it happens very often right as the game starts so before drop-off. Had a few games where I haven't noticed the issue happening at all, which makes me wonder if it is related to a laggy server in some way.
Editing to be more specific, this only lasts for a brief moment, usually a few seconds, never longer than 10 seconds or so. It does happen very frequently over the duration of the game so it is quite disruptive. Haven't checked if the actual sensitivity setting value changes, it just feels like the sensitivity goes to 0,1.
