Okay then. I swapped in a Razer mouse of mine which I do not use anymore, and changed Synapse settings for my world of Warcraft profile to have a polling rate of 125.
This is NOT a solution. The jumping still occurs, and still doesn’t have a solution.
Still curious for more troubleshooting since this issue doesn’t seem to affect enough players for them to actually look into it. I can replicate the issue pretty easily.
Edit: Please fix Raw Mouse Input - #5 by Enthyx-emerald-dream <---- link
Finally found this thread after seeing it once then not being able to find it again. Even has the polling rate solution in it, which surprised me. It also includes the blue post stating that this is a known issue which I mentioned previously. Just incase providing a link to this can get somewhere…….
