I'm having the same issue. Plugin works fine 816x624, but when I use 1104x624, cursor is completely off center.
Hi! How are you? I'm sorry you're having issues with the plugin.
I've tried using the plugin with the screen resolution you mentioned and I haven't found any visual or functional errors (I'm attaching some photos).
Could you please send me a demo of the project you're using via private message so I can open it on my setup and see what issue you're experiencing?
Also, if you attach photos, videos, and more details about the problem, that would be ideal since I need to replicate the error in order to investigate and fix it.
Best regards!
