Mumble effecting mouse

[megawac]

Lately I have been having a pretty persistent mouse problem while running source engine games (l4d, l4d2 and tf2). Sporadically the mouse will begin moving unpredictably and erratically, either accelerating ridiculously fast or "snapping" at pretty consistent angles somewhere between 30 and 45 degrees instead of moving smoothly.

This error began coming up on June 30th after a windows update (which I then assumed was the cause). I tried to find the problem by rolling back/updating drivers, I bought a new (different brand) mouse, changed all the windows mouse settings, etc.. None of those helped. I eventually isolated the problem to only occur while mumble was running so I tried reinstalling and reverting to older versions which did not help at all.

I'll try to record a video of the issue because it is pretty hard to describe and when I do it over mumble people always accuse it as an excuse but it makes games almost unplayable.

Thanks for reading, I'll try to help in any way possible.

P.S. This guy seems to have a similar issue, except its his mouse is just going to the middle, not snapping/accelerating.

*Edit* Retyped in more detail

**Edit Snapshots didnt help :(

For me this is a new issue.

You state that the effect only happens when running source engine based games. Probably one of the auto updates of steam is causing this problem. I do not have a solution at the moment. I have some source engine based games, so I can try to replicate the problem.

Rewrote it so it better describes the issue.

Another thought. If this issue will not be fixed in a foreseeable amount of time, is there any "cheat fixes", like to limit/remove the program's interaction with the mouse or something?

Thanks!

This is just a guess, but you could try to disable the plugins and/or overlay. These are the only two things that really interact with the games memory. If it helps, could you provide us which of the two systems is causing the problem.

Tried that already. No effect.

Todays Windows update may have fixed the issue, will update this post tomorrow.

I lied. The issue still occurs (less often?) then before. I've tried using versions 1.2.3 and 1.2.1; is still occurs in both still (1.2.3. more often).

same here never used the program before and it makes games unplayable. teamspeak and vent all work fine for me so i dont know what it is. its not my cpu it has to be a conflict somewhere.
