sv_cheats 1 mouse freakout

Every time I put sv_cheats to 1, my side-to-side mouse movement drops to basically zero, and my up-and-down mouse movement skyrockets, making the game completely unplayable with sv_cheats 1.

I completely reinstalled the game, kept no .cfg files, and only a few addons which thousands of people use with no issues. This happens on singleplayer, or multiplayer, I reset my keys to default, fresh installed the game, checked online and found nothing about this issue, so I came here as my last resort. Uploading a video of it to youtube to show what I mean if I didn’t describe clear enough.

Well that fixed it. I tried it before, but not since my clean up job. Thanks.
