Mouse jumps, but only when dragging the screen.

My mouse has recently started jumping around the screen, usually small jumps sometimes quite large but never to the side of the screen like some problems I've heard other people having, the thing is it only happens when using the screen scroll toggle in SC2 (middle mouse button). to make sure its not the middle mouse button being pushed that's causing the issue I rebound the key to my keyboard and I'm still getting the same problem.

I've recently installed some software to stream with and other bits to let me use my kinect as a webcam. I have disabled all the hotkeys on those programs but have never had the problem before and even with those bits of software closed I'm still having the issue. I disabled the windows mouse acceleration a long time ago.

I'm also going to include a link to a video I took of the bug in action so you can see what I'm talking about.

Again this jumping only happens when I press/release the screen drag button and never when just moving the mouse around, also if i keep the mouse stationary and keep hitting the screen drag key the cursor does not move.

The video I took does not show exactly the same thing as i see on my screen, while holding the drag button the mouse cursor vanishes as usual but on the video you can see it jumping around a little. this is not the problem I'm having and if u keep watching the video you can see the screen make a large jump. I'm not sure if this has anything to do with the issue but again I have tried it with no software running.

Any advice on weather i should be using screen drag in Starcraft at all would also be helpful, I'm trying to get to grips with the camera jump keys now but would also like to keep using the drag to move the screen rather than pushing the mouse cursor on the edge of the screen but I'm open to any input you would like to make on this.

Thanks in advance for any help you can offer its so good of you to spend your time trying to help people!

This is why I eventually stopped using the drag screen function. I've seen posts about this on the official bnet-forums as well, but as usual, no fix incoming. I was able to reproduce this bug on many different machines/setups, so it has nothing to do with streaming software etc.

The only time my mouse cursor skips around is when a piece of skin or fingernail ends up on my mouse-pad and gets "run over" by the mouse; can't say I've ever really had an issue with drag screen causing the camera to make unexpected movements. Sounds like a very weird issue that doesn't happen to everyone. I don't ever see it happening in pro games with a spectator, and they use the drag screen function a lot.

Yea drag scroll sometimes makes massive jolts in an unexpected direction. It's much worse at super low DPI

Some guy wrote an maybe solution and Explanation to the problem. It didnt work for me though.

http://us.battle.net/sc2/en/forum/topic/8197581067?page=1#6


is there any other solution to this? Its really hard to play, and it costs seconds and confuses...


edit: sry wrong link..

heres an example: http://drop.sc/355523

at 4:13 (ingame) the screen just jumps half-screen left at the nexus! I checked the replay with SC2Gears - to see if there is maybe some strange command or sth. but there isnt!
