Good morning,
Sorry if there is a topic already on this issue.
The right mouse click sometimes is not “sticking” when I turn the camera. If I keep it pressed and turn the camera it’s like it’s clicking-unclicking very fast. Hope I made myself understood. 
It’s really frustrating because many times when I want to turn the camera it unsticks and I attack a random mob or is horror in dungeons and so on.
Thank you and have a great day,
Sorry to hear that your right click may not be lasting properly. It does sound like your right click may be dying a little bit.
Before anything else, I’d test this. To do this on windows navigate to control panel, click mouse then tick switch primary and secondary buttons.
Once done, open MSpaint or any drawing program and start drawing lines. This should allow you to work out if the issue lies with your mouses right click or a game setting. ^^
Hello,
Thank you for your reply. Unfortunately the issue is still there. The issue is not present outside WoW and I have tested another mouse. I have searched the issue and there is a command line, but it’s still not working.
Thank you and have a nice evening
Hello Kalingrom 
We have seen this kind of behaviour connected to some third party software, more specifically Razer Chroma.
If you have any Razer software installed on your system can you please try removing them and check if the situation improves?
If you don’t mind I would like you to also try the steps suggested in this article. The problem described there is a bit different than yours, but the covered steps are still valid for your case as well ^^
Hello Felranys and Mosinathus,
Indeed it is from my mouse. I have tested it on a website where you keep the mouse clicked and you see a “light” if it’s working and indeed it stops for fractions of seconds. Tested the 3rd mouse today and is working fine (laptop normal mouse). So will have to buy a new one for gaming now hehe.
Thank you for your support and have a nice day,
Thanks for the update Kalingrom, appreciated!
Enjoy your day you too, and take care! ^^
I also Experience the right click issue problem since Phase 4 in Classic wow that ruins my gameplay and the fun aspects of the game significantly. I tried many things to fix this but nothing worked. Can you share me the site to test my mouse as well?
Hello Keadas,
I cannot remember the site, but please try to search with mouse click test keywords (can’t remember). When you click please move the mouse as well to see if it “disconnects” the click when you move the mouse.
Have a great day,
Im also having the same problem and I suspect its been raised here but Im not sure if its exactly the same issue: Mouse lag since hotfix? - #4 by Kalahane-chogall
Either way, in my case this happens for 3rd reset day in a row - It sort of goes away after I play with the console commands for the mouse as suggested in the thread and then goes worse particularly on every Wednesday. No other game I play or out of wow situation has the same problem and I also reported it in-game (not sure if I will get a reply but havent so far). In fact, Overwatch where I am much more sensitive on how my mouse works has been just fine.
New update about my case, seems like out of nowhere i solved my issue after i started to experience the same problems after i installed my old school mmorpg Warhammer online. I’ve started again to dig deeper on some fixes for one last time before i came in to conclusion that probably my mouse was dying after all but to be 100% certain, i need to test it on massive pvp-raiding scenarios . What i did was to uninstall Razer synapse 3 and 2, Glary utilities and Device manager mouse drivers, restarted my pc and then i used a different usb port for my mouse and i updated my mouse from my device manager this time not from razer synapse. Dont install Razer synapse at all but now you may experience the lift of calibration issue some times but its better compare to our original issue that makes this game unplayable.
I exited logitech software, and the problem was gone.
