This is odd but what’s your windows display upscalling up too? The thing that increases windows icons Taskbar and so on high res monitors
I’ve fixed it. Here’s what I did, and I hope it works for you.
I have two OS drives - one for general work and to install any programs (experimental or otherwise) that I want; and the other purely for gaming. This second drive has nothing installed but games. No 3rd party apps run on startup. It’s as clean as can be. The Nvidia drivers are all I can think of. No addons of any kind in WoW.
Anyway, I decided to give WoW a crack on that second drive. Perfect performance. No mouse issues of any kind.
So I went back to my main OS and ran WoW again. Both problems were still present. I then tried disabling background programs. Unfortunately, I quit a few at a time, but I narrowed it down pretty nicely. For me, it was 100% either a program called Dual Monitor Tools, or (most likely) the AutoHotkey scripts I run (7 in total). If you use either of these programs, try disabling it. The instant I quit them, the cursor again worked as intended.
I realize this probably won’t fix your issue, OP (you mentioned you already disabled unnecessary programs), but maybe it will solve someone else’s problem down the road.

Well my mouse issues came back after a fresh windows install last december when i upgraded my SSD, before that i never had the issue since bfa prepatch. WoW is the only thing i ran on the computer and it still had the mouse issues.
I am having the same issue even with raw input set to 0.
Had this issue since BFA launch. Read all the threads but ended up reinstalling windows. All was well until today. What was different? I installed origin game launcher. Whenever it ran in the background, the cursor would jump to the middle of the screen whenever I clicked RMB or LMB and moved the camera. If origin can cause this, potentially other 3rd party programs can. Just thought I would throw this info out to help anyone with this extremely frustrating bug.

Ive had this problem for years, Do you use the Geforce Overlay, by chance?
Uhh So I’ve had this issue since the beginning of legion. I’ve tried so many things, then only today I tried exiting the Battlenet app. Seemed to fix it right away…

Making this post to report that I have the exact same problem. It’s driving me CRAZY!
EDIT: So just to be thorough, I’m going to go through all the fixes posted in this thread.
Modified UI reset, posted by Joynueer: No dice. Mouse still randomly jumps to the middle of the screen when right clicking while moving the mouse.
Screen Mode, posted by Joynueer: No dice.
DPI scaling, posted by Joynueer: No dice. If anything, the problem got significantly worse with this “fix”.
Windows Mouse Compatibility, posted by Joynueer: The link leads to a 404.
Lower mouse Polling Rate to 125, posted by Zungar: Lowering the polling rate to 125 with 250 DPI sensitivity seems to have significantly reduced the problem, but it still happens occasionally. Downside is that my mouse moves much slower… hrm. (For the record, my polling rate was 500 with 1000 DPI sensitivity before.)
EDIT 2: Honestly, I’m satisfied with the significantly reduced mouse teleporting rate with the polling rate set to 125. The settings I’m using for my Logitech mouse now is 125 polling rate, 500 DPI sensitivity (so my cursor doesn’t move as slow as a turtle).
You can still set the sensitivity higher. To the best of my knowledge it was only the polling speed that was an issue.

Yeah, figured that out right before you made your post. 
Thanks, though!

Hey all,
This is an old thread, and typically I’d lock it, but since folks keep finding it and it discusses an ongoing investigation, I’m just going to update it. Since this post, we’ve created an article with the known work arounds for various issues. Unfortunately this is a bit more difficult to unravel than most issues as it is actually several totally different bugs with similar behavior. You can check the article here for troubleshooting advice, but the bugs are still on our radar.
oh dang, nice. thanks for the tip-off!! closing Bnet solved this 100% for me, hope that helps someone else down the road. this has been driving me nuts since early Legion

I got a new mouse and had the same issues. I did some searching and found this console command that fixed it. You’ll just have to change the mouse settings to your liking afterwards.
/console rawMouseEnable 1

Having a similar issue. Driving with my right mouse button causes erratic jumping. Sometimes, when I’m flying and I try to turn, I will often take a nose dive or a really sharp turn. It happens frequently and somewhat randomly.
Using a Razer Naga Trinity mouse. I was having an issue where the right mouse button wouldn’t recognize me pressing it or if it did recognize it then it would stop or cut out when I was holding it down while moving. I tried various steps of turning off all addons, changing dpi settings and other various suggestions. I finally found this post which led me to the article in the last customer service post. The first step in that post gave me the solution. I just had to un-check mouse sensitivity and I no longer have the issue. I would recommend making that article easier to find as I have been working to fix this problem since the anniversary event started.
I’m getting this exact problem (holding down right click with camera) i’ve tried all those solutions, but yet to find a fix. I have the same mouse as @Azoun as well (Razer Naga Trinity)
Update…While it fixed it for a night, it is back to not sticking when holding down the right button.
Reposting from my thread to this thread, since it seems to be the same issue:
These are two separate issues, so I’ll explain them separately. First, the mouse cursor continuing to move while holding left or right click to move the camera.
When rawMouseEnable cvar is set to 1 (raw mouse input enabled), occasionally (approximately 5% of the time), the mouse cursor will continue moving while left or right-click is held down to rotate the camera. This causes the cursor to appear to “jump” across the screen, when it is expected that it should remain in place. This issue has persisted across multiple mice - Currently I use a Corsair Ironclaw RGB, but previously I had the same issue with a Mionix NAOS 7000 and Logitech mx518.
I’ve attempted the following fixes: Setting the mouse polling rate to 125 (matching the cvar rawMouseRate), disabling foreground DPS limiting, disabling browser hardware acceleration in the battle.net client, disabling mouse sensitivity, adjusting the DPI of the mouse down to 400 to match the rawMouseResolution cvar, disabling rawMouseAccelerationEnable cvar, disabling Fullscreen Optimization (win10 feature) for the WoW client. So far, none of these options have improved the issue for me.
I have tried these fixes for the previous issue, and also the following issue:
When rawMouseEnable cvar is set to 0 (raw mouse input disabled), at approximately the same rate as my previous issue, the mouse cursor will reset its position to approximately the position of my character onscreen (what I believe to be a 0,0 offset for UI elements). This can either cause the cursor position to reset, or more often, the camera to suddenly jerk in one direction, as the cursor jumps back to its previous position. Obviously this is an incredible hindrance in gameplay.
I believe these issues to be fundamentally related, but for the life of me I’ve never been able to solve them. They are always mutually exclusive for me, and depend on whether I am using raw mouse input. They have persisted for years, ever since approximately the Warlords of Draenor expansion. And they have persisted over multiple OS installs, from several Win7 installs and now on Win10. My Video card has changed a few times (but has always been nvIdia, though I do not use GeForce Experience). Drivers are all up to date.
I am officially out of ideas. World of Warcraft (both retail and classic) is the only game that I have this issue in. If anyone has any suggestions for possible solutions, please let me know.

I had this issue but it was solved by locking my mouse to the window in Interface > Mouse and check to enable lock cursor to window.
Sometimes after large patches or reinstalls or resetting ui this gets unchecked and it acts up again, the moment it does i check and sure enough it became unchecked. Checking it so it is enabled stops the rapid mouse movement, for me at least.
Hope this helps some people.
Tried this as well, does not appear to fix the issue or reduce the frequency.
